NPTL cannot be used at all without that kernel support.
__ASSUME_CLONE_THREAD_FLAGS is used by system.c, which is
just using CLONE_PARENT_SETTID and not being able to use that
just renders some obscure cancellation case buggy as opposed
to rendering system unusable.

I think it is indeed moot now with the new minimum kernel versions we are
going to switch to.  But it did make sense at one time.


Thanks,
