Sorry about that.  I apologise.

Adding objc to the languages does not even build libffi.  Fudging the
targets in configure to make it build means it also installs with an
FSF build, but Apple use build_gcc to assemble the final distribution
and it does not copy ffi.h into its final location without a patch like
I suggested.

I will stick it on Apple's bug reporter as a suggestion.
