Created attachment 221097 [details] build.log The same happens with gnat-gcc-4.3.2
Created attachment 221099 [details] config.log also happens with 4.3.2
There you have it :-) sorry for the long delay.
and here's the issue, gnatgcc doesn't understand core2 arch: configure:3197: /var/tmp/portage/dev-lang/gnat-gcc-4.3.2/work/usr/bin/gnatgcc -O2 -march=core2 -pipe -L/var/tmp/portage/dev-lang/gnat-gcc-4.3.2/work/usr/lib/gnatgcc/i686-pc-linux-gnu/4.1 conftest.c >&5 conftest.c:1: error: bad value (core2) for -march= switch conftest.c:1: error: bad value (core2) for -mtune= switch and because of that, it fails when trying to compile anything: configure:3239: error: C compiler cannot create executables

So you shouldn't use invalid cflags for older compilers.
