So.. I am not a strong C guy. If you check this message, it appears that __WORDSIZE is not being set correctly for ppc64. If I look at ffi/ext/ffi_c/libffi/configure I see:

        ppc64-*linux*|powerpc64-*linux*)
          LD="${LD-ld} -m elf32ppclinux"
          ;;


Is this correct? Should it be calling 32 bit libraries

Word of warning.. I am no too familiar with C across platforms.  I am
trying to package ruby-ffi (spec file is at [1]) and when I do a scratch
build in Koji [2] it runs fine on x86 but is failing in ppc_64. It
appears that __WORDSIZE is not being set [3]. I looked at the CFLags for
the x86_64 and they are the same, so I assumed things would run fine.
Can anyone point me at what to look at next?
