+Subject: [PATCH] configure: allow cross-compilation
+
+Some compilers are in fact a wrapper (e.g. to speed compilation with
+ccache or distcc, or as a cross-compiler wrapper). Those wrappers may
+not properly recognise the -v option, or may internally enforce some
+flags that conflict with -v.
+
+Use --version as a fall-back.
+
+With --version. the compiler will report its executable's basename, e.g.
+arm-linux-gcc not gcc. Catter for that by grepping for the compiler
+family name.

+[yann.morin.1998@free.fr:
+  - retain "$CC -v" as default, fallback to "$CC --version"
