I haven't actually built it yet (was waiting as long as I could to see if
this would be done officially). Generally speaking the first step is
changing the gcc/libstdc++ version in the spec and then fix up any minor
issues afterwards, but in order to actually install and use it you need to
rebuild the other packages that depend on it (in a default Fedora setup
that's mainly Mesa) . Mesa is one package I definitely don't understand
which is why I don't like the idea of doing llvm myself.

The other alternative is what I would likely do instead and do a parallel
installable package which of course requires a bit more thought since a lot
of the libs are by default unversioned.

If it does turn out I have to do this myself though I will see about
putting a repo on fedorapeople and announce it here for those that
want/need it.
