What we were talking about in this subthread was about a depency on
clang, not LLVM. And that's just needed at buildtime, to generate the
bitcode files (including synchronizing types / function signatures).

For the, which already depends on EPEL, there's a new enough
LLVM version. There's a new enough version in RHEL proper, but it
appears to only be there for mesa (llvm-private).
