+Subject: [PATCH] Fix BLAS library integer size detection
+
+When cross-compiling, octave ./configure script fails to detect the BLAS
+library integer size and fails with the message:
+
+    configure: error: unrecognized BLAS library integer size
+
+This patch fixes this detection.
+
+Patch adapted from:
+https://github.com/openembedded/meta-openembedded/commit/0ad153f721ef99de585c4452a997a7104f45d71d

+	  GNU Octave is a high-level language, primarily intended for
+	  numerical computations. It provides a convenient command
+	  line interface for solving linear and nonlinear problems
+	  numerically, and for performing other numerical experiments
+	  using a language that is mostly compatible with Matlab. It
+	  may also be used as a batch-oriented language. Octave has
+	  extensive tools for solving common numerical linear algebra
+	  problems, finding the roots of nonlinear equations,
+	  integrating ordinary functions, manipulating polynomials,
+	  and integrating ordinary differential and
+	  differential-algebraic equations. It is easily extensible
+	  and customizable via user-defined functions written in
+	  Octave's own language, or using dynamically loaded modules
+	  written in C++, C, Fortran, or other languages.
