[autoconf-conversion] libffi take 2

Very good, I will put up a final patch for libffi tomorrow.  So now there's gas,
fastjar, libffi, and libiberty (I don't remember well about the latter).

Yes, though I had to do some of the work that went into this patch.

It is about converting the gcc and src repositories to Autoconf 2.5x
and Automake 1.7.  It was announced about a week ago on the gcc mailing list.
