The following patch is intended for the 3.4 branch; in the trunk,
there is no longer a gcc/libffi/configure.in file.

I verified that it works correctly on alpha-dec-osf5.1 with autoconf 2.13.

If approved, I will need for someone else to apply the patch.

	* configure.in: Test for existence of mmap before checking
          blacklist.  Fix suggested by Jim Wilson.
