+# Copy the full external toolchain sysroot directory to the staging
+# dir. The operation of this function is rendered a little bit
+# complicated by the support for multilib toolchains.
+#
+# We start by copying etc, 'lib', sbin, usr and usr/'lib' from the
+# sysroot of the selected architecture variant (as pointed to by
+# ARCH_SYSROOT_DIR). This allows to import into the staging directory
+# the C library and companion libraries for the correct architecture
+# variant. 'lib' may not be literally 'lib' but could be something else,
+# e.g. lib32-fp (as determined by ARCH_LIB_DIR) and we only want to copy
+# that lib directory and no other. When copying usr, we therefore need
+# to be extra careful not to include usr/lib* but we _do_ want to
+# include usr/libexec.
+# We are selective in the directories we copy since other directories
+# might exist for other architecture variants (on Codesourcery
+# toolchain, the sysroot for the default architecture variant contains
+# the armv4t and thumb2 subdirectories, which are the sysroot for the
+# corresponding architecture variants), and we don't want to import
+# them.
+#
+# If ARCH_LIB_DIR is not a singular directory component, e.g.
+# 'lib32/octeon2', then symbolic links in ARCH_LIB_DIR and
+# usr/ARCH_LIB_DIR may be broken because Buildroot will flatten the
+# directory structure (e.g. lib32/octeon2/foo is actually stored in
+# lib/foo). This is only relevant for links that contain one or more ../
+# components, as links to the current directory are always fine.
+# We need to fix the broken links by removing the right amount of ../
+# dots from the link destination.
+# Once the link destination is valid again, it can be simplified to
+# remove the dependency on intermediate directory symlinks.
+#
+# It is possible that ARCH_LIB_DIR does not contain the dynamic loader
+# (ld*.so or similar) because it (or the main symlink to it) normally
+# resides in /lib while ARCH_LIB_DIR may be something else (e.g. lib64,
+# lib/<tuple>, ...). Therefore, copy the dynamic loader separately.
+#
+# Then, if the selected architecture variant is not the default one
+# (i.e, if SYSROOT_DIR != ARCH_SYSROOT_DIR), then we :
+#
+#  * Import the header files from the default architecture
+#    variant. Header files are typically shared between the sysroots
+#    for the different architecture variants. If we use the
+#    non-default one, header files were not copied by the previous
+#    step, so we copy them here from the sysroot of the default
+#    architecture variant.
+#
+#  * Create a symbolic link that matches the name of the subdirectory
+#    for the architecture variant in the original sysroot. This is
+#    required as the compiler will by default look in
+#    sysroot_dir/arch_variant/ for libraries and headers, when the
+#    non-default architecture variant is used. Without this, the
+#    compiler fails to find libraries and headers.
+#
+# Some toolchains (i.e Linaro binary toolchains) store support
+# libraries (libstdc++, libgcc_s) outside of the sysroot, so we simply
+# copy all the libraries from the "support lib directory" into our
+# sysroot.

+# External toolchain package infrastructure
+#
+# This package infrastructure implements the support for external
+# toolchains, i.e toolchains that are available pre-built, ready to
+# use. Such toolchain may either be readily available on the Web
+# (Linaro, Sourcery CodeBench, from processor vendors) or may be built
+# with tools like Crosstool-NG or Buildroot itself. So far, we have
+# tested this with:
+#
+#  * Toolchains generated by Crosstool-NG
+#  * Toolchains generated by Buildroot
+#  * Toolchains provided by Linaro for the ARM and AArch64
+#    architectures
+#  * Sourcery CodeBench toolchains (from Mentor Graphics) for the ARM,
+#    MIPS, PowerPC, x86_64 and NIOS 2 architectures. For the MIPS
+#    toolchain, the -muclibc variant isn't supported yet, only the
+#    default glibc-based variant is.
+#  * Synopsys DesignWare toolchains for ARC cores
+#
+# The basic principle is the following
+#
+#  1. If the toolchain is not pre-installed, download and extract it
+#  in $(TOOLCHAIN_EXTERNAL_INSTALL_DIR). Otherwise,
+#  $(TOOLCHAIN_EXTERNAL_INSTALL_DIR) points to were the toolchain has
+#  already been installed by the user.
+#
+#  2. For all external toolchains, perform some checks on the
+#  conformity between the toolchain configuration described in the
+#  Buildroot menuconfig system, and the real configuration of the
+#  external toolchain. This is for example important to make sure that
+#  the Buildroot configuration system knows whether the toolchain
+#  supports RPC, IPv6, locales, large files, etc. Unfortunately, these
+#  things cannot be detected automatically, since the value of these
+#  options (such as BR2_TOOLCHAIN_HAS_NATIVE_RPC) are needed at
+#  configuration time because these options are used as dependencies
+#  for other options. And at configuration time, we are not able to
+#  retrieve the external toolchain configuration.
+#
+#  3. Copy the libraries needed at runtime to the target directory,
+#  $(TARGET_DIR). Obviously, things such as the C library, the dynamic
+#  loader and a few other utility libraries are needed if dynamic
+#  applications are to be executed on the target system.
+#
+#  4. Copy the libraries and headers to the staging directory. This
+#  will allow all further calls to gcc to be made using --sysroot
+#  $(STAGING_DIR), which greatly simplifies the compilation of the
+#  packages when using external toolchains. So in the end, only the
+#  cross-compiler binaries remains external, all libraries and headers
+#  are imported into the Buildroot tree.
+#
+#  5. Build a toolchain wrapper which executes the external toolchain
+#  with a number of arguments (sysroot/march/mtune/..) hardcoded,
+#  so we're sure the correct configuration is always used and the
+#  toolchain behaves similar to an internal toolchain.
+#  This toolchain wrapper and symlinks are installed into
+#  $(HOST_DIR)/bin like for the internal toolchains, and the rest
+#  of Buildroot is handled identical for the 2 toolchain types.

+# Various utility functions used by the external toolchain package

+#
+#   - installation the toolchain libraries to $(TARGET_DIR)
+#   - copying the toolchain sysroot to $(STAGING_DIR)
+#   - installing a gdbinit file
+#
+# Details about sysroot directory selection.
+#
+# To find the sysroot directory, we use the trick of looking for the
+# 'libc.a' file with the -print-file-name gcc option, and then
+# mangling the path to find the base directory of the sysroot.
+#
+# Note that we do not use the -print-sysroot option, because it is
+# only available since gcc 4.4.x, and we only recently dropped support
+# for 4.2.x and 4.3.x.
+#
+# When doing this, we don't pass any option to gcc that could select a
+# multilib variant (such as -march) as we want the "main" sysroot,
+# which contains all variants of the C library in the case of multilib
+# toolchains. We use the TARGET_CC_NO_SYSROOT variable, which is the
+# path of the cross-compiler, without the --sysroot=$(STAGING_DIR),
+# since what we want to find is the location of the original toolchain
+# sysroot. This "main" sysroot directory is stored in SYSROOT_DIR.
+#
+# Then, multilib toolchains are a little bit more complicated, since
+# they in fact have multiple sysroots, one for each variant supported
+# by the toolchain. So we need to find the particular sysroot we're
+# interested in.
+#
+# To do so, we ask the compiler where its sysroot is by passing all
+# flags (including -march and al.), except the --sysroot flag since we
+# want to the compiler to tell us where its original sysroot
+# is. ARCH_SUBDIR will contain the subdirectory, in the main
+# SYSROOT_DIR, that corresponds to the selected architecture
+# variant. ARCH_SYSROOT_DIR will contain the full path to this
+# location.
+#
+# One might wonder why we don't just bother with ARCH_SYSROOT_DIR. The
+# fact is that in multilib toolchains, the header files are often only
+# present in the main sysroot, and only the libraries are available in
+# each variant-specific sysroot directory.
+
+
+# toolchain_find_sysroot returns the sysroot location for the given
+# compiler + flags. We need to handle cases where libc.a is in:
+#
+#  - lib/
+#  - usr/lib/
+#  - lib32/
+#  - lib64/
+#  - lib32-fp/ (Cavium toolchain)

+	  Linaro toolchain for the ARM big endian architecture. It
+	  uses Linaro GCC 2018.05 (based on gcc 7.3.1), Linaro GDB
+	  2018.05 (based on GDB 8.1), glibc 2.25, Binutils 2018.05
+	  (based on 2.28). It generates code that runs on all Cortex-A
+	  profile devices, but tuned for the Cortex-A9. The code
+	  generated is Thumb 2, with the hard floating point calling
+	  convention, and uses the VFPv3-D16 FPU instructions.
