The attached change results in a successful build of sort.
I'm afraid that won't work, because it assumes that the

I don't see that it assumes that the application uses both threadlib
and pthreads. As far as I can tell, sort doesn't use threadlib.
It uses pthreads. Thus, a fallback is needed when pthreads
is not available. If we are not using pthreads, we get a trivial
pthread implementation from lib/pthread.h with the change.
It seemed reasonable to base this on the configure variable
USE_POSIX_THREADS. We could get the same result by
modifying the configure result for HAVE_PTHREAD_H, etc,
but the system does have a pthread.h header. It's just not
usable.
Another alternative might be to convert sort to use threadlib.
