[PATCH] D9639: Do not include pthread.h and sched.h when threads are disabled

[Jonathan Roelofs]

jroelofs added a comment.

I get away with not having the guard in <__mutex_base> because all the places where these two headers are used have:

  #ifdef _LIBCPP_HAS_NO_THREADS
  #error <thread> is not supported on this single threaded system
  #else // !_LIBCPP_HAS_NO_THREADS

The one in mutex, I think, is a result of me not having rebased in a _long_ time, and the buildbot for it not testing exactly the same setup as me.
