Comment (by kencu):

 during bootstrap of 10.6.8, `llvm-3.4` builds using the stock toolchain.
 Then `clang-3.4` can be built, having a build dependency on `cctools` at
 that point. So the only llvm variant available for cctools during
 bootstrap is `llvm-3.4`.

 Once clang-3.4 is built, it can then build clang-3.7, and then that can
 build llvm/clang-5.0.

 So there does not appear to be a way to build cctools with `llvm-5.0` from
 the outset using the stock toolchain. You would have to go through a
 `cctools +llvm34` stage to get to `cctools +llvm50`.
