[Libffcall] libffcall tar downloads

[Hernán Erasmo]

The latest tarball can be downloaded from here https://github.com/libffcall/libffcall/archive/ffcall-1.12

I've set up a mirror on Github to try to take advantage of it's Release feature, since I can't get the people from Savannah to give me acces to ftp uploads.
