Title: Only use -arch ppc on Darwin when running on powerpc.

Recent XCode versions now use LLVM for compilation, and do not ship
powerpc support. This causes FFI spec fixtures to fail compilation.
By masking -arch ppc to only be used on powerpc, we avoid this
issue, and a mixed x86+ppc universal binary is not necessary for
testing purposes.
