Really these checks should be at the top of the configure script.
On Cygwin where it takes about 10 minutes to do the configure,
it is a bit frustrating that these likely-to-fail checks are last.

Also, is the libunistring dependency still necessary, since
Guile's moved to its own iconv-based conversion?  If there are
only a few libunistring functions left, maybe we should try to
get rid of them or use gnulib for the rest.

On Fedora at least, libffi's been packaged for a long time.  I think
it is widely available generally as a pre-built package.
