* sysdeps/mach/hurd/pt-sysdep.h (_HURD_THREADVAR_THREAD): Remove macro.
(___pthread_self): Declare new __thread variable.
(_pthread_self): Take self pointer from ___pthread_self instead of
threadvar.
* sysdeps/mach/hurd/pt-sysdep.c (___pthread_self): Define new __thread
variable.
(init_routine): Set ___pthread_self to initial thread structure.
* pthread/pt-internal.h (__pthread_setup): Add `self' parameter to
`entry_point' parameter.
* pthread/pt-create.c (entry_point): Add `self' parameter. Store it in
___pthread_self.
* sysdeps/l4/hurd/ia32/pt-setup.c (stack_setup): Add `self parameter to

(first_entry_1): Pass `self' parameter.
(stack_setup): Add `self' parameter to `entry_point' parameter, pass it the
`thread' parameter.
(__pthread_setup): Likewise.
