   it is passed so we cannot pretend that the interface is active if -pthreads

   we need to play the usual game with weak symbols.  On Solaris 10 and up, a
   working interface is always exposed.  On FreeBSD 6 and later, libc also
   exposes a dummy POSIX threads interface, similar to what Solaris 2.6 up

   have no functionality.  The details are described in the "libc cumulative

   provided for checking whether an application is linked to a shared pthread
   library or not.  However, these interfaces aren't available in early
   libpthread libraries.  We also need a test that works for archive
   libraries.  We can't use pthread_once as some libc versions call the
   init function.  We also can't use pthread_create or pthread_attr_init
   as these create a thread and thereby prevent changing the default stack
   size.  The function pthread_default_stacksize_np is available in both
   the archive and shared versions of libpthread.   It can be used to
   determine the default pthread stack size.  There is a stub in some
   shared libc versions which returns a zero size if pthreads are not
   active.  We provide an equivalent stub to handle cases where libc
   doesn't provide one.  */
