What I mean is the failure of this test (whether `pthread_create()` is
defined within libpthread) does not mean `pthread_create()` is not present at
all, nor that the test for `pthread_setattr_default_np()` need not be performed.
This test is essentially a check for whether libpthread needs to be linked
in. If it fails, `pthread_create()`, etc. are still used; POSIX threads are
then simply assumed to be part of libc.
