I am using

--enable-languages=c,c++,objc,fortran,obj-c++,java,ada --disable-libgcj

which formerly disabled building of libffi, but now leaves it enabled
(even if go is not enabled).

I didn't remember that, so maybe the issue isn't that important.  But
maybe we can have a --disable-libffi configure option?  (continuing
to disable libffi with --disable-libgcj if Go is not build would be
also ok of course).
