We have several other libraries in the GCC repo where the official upstream
lives elsewhere.  There is usually a README.gcc explaining the rules of
contributing, usually only very small bugfixes that are urgently needed are
accepted temporarily into GCC without going to upstream first, otherwise
people should go the upstream way and the fixes are either merged using full
merges from upstream, or cherry-picked if they are needed faster.
So, libffi after merging all the GCC improvements could be switched to
similar mode.
