Comment (by kencu):

 of course, simple oversight on the rewrite perhaps. I'll check for the dep
 and add it if needed.

 Originally I was thinking to build libomp with everything else clang-12
 builds rather than have this separate libomp port, but in the end I
 changed it back to using the libomp port. I'm still not 100% sure that is
 the best idea....but testing is hard

 For example, does clang-3.7 really work properly with libomp from the
 llvm-12 tree??
