Great, thanks!

Regarding the PowerPC result at
http://autobuild.buildroot.org/results/d45/d459457d0046cf96b56c5fc0660eca326d90401d/build-end.log,
it looks weird, because the code is:

#elif defined(__ppc__)
#define GOOGLE_PROTOBUF_ARCH_PPC 1
#define GOOGLE_PROTOBUF_ARCH_32_BIT 1
#elif defined(__GNUC__) && \
 (((__GNUC__ == 4) && (__GNUC_MINOR__ >= 7)) || (__GNUC__ > 4))
// We fallback to the generic GCC >= 4.7 implementation in atomicops.h
# if __LP64__
#  define GOOGLE_PROTOBUF_ARCH_64_BIT 1
# else
#  define GOOGLE_PROTOBUF_ARCH_32_BIT 1
# endif
#else
#error Host architecture was not detected as supported by protobuf
#endif

Since the failure is on PowerPC, __ppc__ should be defined, and we
shouldn't have the #error.

Maybe Gustavo, you know if __ppc__ is not defined on certain PPC platforms?

Thanks,

Thomas
