your patch broke darwin libffi

[Andreas Tobler]

Hi David,

your latest patch to the libffi broke darwin to build:
/Volumes/xufs/gccsrc/objdir/gcc/xgcc -B/Volumes/xufs/gccsrc/objdir/gcc/
-B/Volumes/reserved1/gcctmp/powerpc-apple-darwin5.2/bin/
-B/Volumes/reserved1/gcctmp/powerpc-apple-darwin5.2/lib/ -isystem
/Volumes/reserved1/gcctmp/powerpc-apple-darwin5.2/include -fexceptions
-g -o ffitest -shared-libgcc src/ffitest.o  ./.libs/libffi.a
/usr/bin/ld: Undefined symbols:
_ffi_call_AIX
collect2: ld returned 1 exit status
make[2]: *** [ffitest] Error 1

I'll have a look what's going on.

Thanks,
Andreas
