r67713 fails to build

I tried an optimized x86_64 build and it fails:

anyone else seeing this?

Curious, a clean rebuild works just fine, so the issue is that there aren't enough dependencies somewhere. :frowning:

If you did a 'make' in the clang directory the tblgen binary wasn't being rebuilt. I fixed this particular crash a few days ago.
