My issue was trying to have libffi built along with gcc without  
building gcj (which is sooooo long to compile).  It's not so  
important now because I happened to also need gcj since then :-)   
It's just that I thought --enable-languages=objc should trigger  
libffi even though java is not built.

Thanks for all the precisions.
