[Buildroot] [git commit] protobuf: limit to supported architectures

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=8677473035cc3e02281c8998c25d6dfa071f3b54
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

protobuf 2.5.0 adds an atomic operations implementation that is limited
to a few architectures only. mips64el and armeb don't work either.

Fixes (among others)
