 You don't need to specify both _HAS_THREADS and HAS_THREADS_NPTL - the second
impies the first.

 Also in the comment you can put "NPTL threads" instead of "threads, ..., NPTL".
Oh, and it's NPTL (New Posix Threads Library), not NTPL.

 Same here of course.

 And finally: don't forget to propagate to the reverse dependencies. Yes, it is
terribly annoying, but Kconfig has no way to avoid it.
