[Buildroot] [git commit] gcc: add patches for powerpc e6500 64-bit support

commit: http://git.buildroot.net/buildroot/commit/?id=71b0ebd92d887c3c6b319e8d57c46db0274aa231
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Building with -mtune=e6500 led to build failures in glibc (probably in
uclibc as well) because gcc was built for a 32-bit target even though
the target tuple is powerpc64-*. This lead to a mix of 32-bit and
64-bit support and build errors like:

  fatal error: gnu/lib-names-32.h: No such file or directory

The root cause is that the configure script is not handling e6500
correctly, because of stupid typo in the condition.

Change has been submitted upstream.
