Andy McFadden b1c9cc2f2d Add memory barriers to pthread_once. ...

The implementation was using a double-checked locking approach that
could break on SMP.

In addition to the barriers I also switched to a volatile pointer.  I
don't think this will matter unless gcc can conclude that _normal_lock
can't affect *once_control, but I figured it was better to be safe.
(It seems to have no impact whatsoever on the generated code.)

Bug 3022795.
