I personally see no need for such option, but it is hard to
know what other people want.
Concerning porting: current Makefile structure worked quite well
for porting to variuous Lisps even if at first port did not
handle FFI. For porting to Poplog I used 'contrib/load-fricas.lisp'
(had to edit it by hand but at some moment it allowed loading
FriCAS even though normal algebra bootstrap would fail in Poplog).
Also, without FFI we would have no gmp for sbcl. With ECL
no C compiler means no compiler at all.
Let me add that I consider making FFI mandatory and using
foreign code to speed up algebra.
