[PATCH] libffi: fix duplicate case on powerpc 32 bit

[Robert Schwebel]

Without this fix, gcc complains about a duplicate case value:

../src/powerpc/ffi.c: In function 'ffi_prep_cif_machdep':
../src/powerpc/ffi.c:670:5: error: duplicate case value
../src/powerpc/ffi.c:667:5: error: previously used here
