270 libpthread libraries. We also need a test that works for archive
271 libraries. We can't use pthread_once as some libc versions call the
272 init function. We also can't use pthread_create or pthread_attr_init
273 as these create a thread and thereby prevent changing the default stack
274 size. The function pthread_default_stacksize_np is available in both
275 the archive and shared versions of libpthread. It can be used to
276 determine the default pthread stack size. There is a stub in some
