+Subject: [PATCH] Fix a build issue with uClibc-ng
+
+uClibc-ng has clock_nanosleep() if built with UCLIBC_HAS_ADVANCED_REALTIME,
+  conflicting with emulation function.

+[Romain:
+    rebase on v1.0
+    remove uClibc legacy support, uClibc-ng provide utmpx.h]

+Subject: [PATCH] Makefile: drop explicit undefine PYLIB for compatibility with
+ make 3.81
+
+GNU make 3.81 does not like the explicit tab-indented undefine:
+
+Makefile:41: *** commands commence before first target.  Stop.
+
+Dropping the indentation also doesn't work:
+
+Makefile:41: *** missing separator.  Stop.
+
+So simply drop the undefine logic.  As explained in the GNU make manual,
+undefine is not commonly needed as E.G. ifdef checks for a non-zero string:
+
+https://www.gnu.org/software/make/manual/html_node/Undefine-Directive.html
+https://www.gnu.org/software/make/manual/html_node/Conditional-Syntax.html

+	  All tools are simple C programs with no dependencies, except

+	  Buildroot configuration.

+	  NPTL implementation of the pthread API (this is always the
+	  case with glibc toolchains, but may not necessarily be the
+	  case with uClibc toolchains, since the thread implementation
+	  is configurable).
