Elephant breaks UFFI's abstractions and assumes SB-ALIEN is being used
behind the scenes. That naturally breaks with cffi-uffi-compat.

CFFI's uffi.asd is just a convenient way of using cffi-uffi-compat
without editing third-party systems and I didn't expect it to be
picked up automatically by tools such as clbuild.

I would gladly rename it. It would work just as well for its original
purpose, since as long as you create a uffi.asd symlink,
(asdf:find-system :uffi) will pick it up. However, I suspect there
might be other code in clbuild that does in fact use cffi-uffi-compat
and I wouldn't want to break it. Can anyone confirm if there is such a
dependency?
