So I had the same problem, and it seems LLVM needs gcc 4.9+. See this thread. Also, these steps worked for me.

Yep, that's right. Like I said, I have a patch here which removes the need for 4.9, but I haven't had the time to merge it in with the big changes which landed last week. Sorry about that. Will try and get it up asap.

Cheers, Ben

@benswift Thank you! I've just tried it on a different computer (still Ubuntu 14.04) which had the same gcc 4.8.4 and I confirm it compiles without problems :) Still having this issue though, but I guess it's something else.

No worries mate.
