Comment (by jfs.world@…):

 Confirmation and patch available at https://sourceware.org/ml/libffi-
 discuss/2014/msg00065.html. The patch is for configure.ac, though, and
 requires a regeneration of 'configure'. It would be simpler (and really,
 that's all that's needed) to simply patch 'configure' directly, and then
 wait for the (soon? hopefully?) new release to be released with the fix
 upstream.

 For now, this patch should do very nicely for macports (I'm only bothering
 to fix lines that will affect macports, btw, in order to keep the patch
 shorter):
