Patch to build lang/gcc6 with system clang
When /usr/bin/cc is clang, lang/gcc5 segfaults trying to stage xgcc compiling
itself. A workaround is to not build lang/gcc5 at all, which is only necessary
for a system that /usr/bin/cc is gcc 4.2.1 and needs >= gcc 4.9 to build
lang/gcc6 which cannot USE_GCC itself and therefore tries to bring in
lang/gcc5...
System tested on:
(qemu) info version
2.12.0
