Uhm I suppose this is the inverted patch.

I fixed the problem in a different way (compiling libracket as a
shared object), your patch should fix it with the static lib but it'll
break the next time libracket will require another library (and is
forcing dependency on libffi even when it is not required), so I
wonder if a more general approach is available (adding pkg-config
support to racket may be an option).
