We are packaging libffi from the separate package instead of gcc in 
Gentoo Linux, and it works very well for Python, Haskell, Java, and so 
forth. Every problem I've seen with it has been pretty much caused by 
unadequate (poor) packaging or missing upstream patches where things 
have already been fixed for the .so.6

So we actually sed the gcc's build system to avoid it:

sed -i -e 's/\(install.*:\) install-.*recursive/\1/' libffi/Makefile.in
sed -i -e 's/\(install-data-am:\).*/\1/' "libffi/include/Makefile.in
