Temporarily revert r60973. It's inexplicably causing a failure when self-hosting LLVM:

llvm[2]: Linking Release executable opt (without symbols)

ld: symbol(s) not found

This is in release mode. To replicate, compile llvm and llvm-gcc in optimized
mode. Then build llvm, in optimized mode, with the newly created compiler.
