Update.
	* pthread.c (__pthread_initialize_manager): Subtract
	TLS_PRE_TCB_SIZE bytes from tcbp to get to descr.
	* manager.c (pthread_handle_create): Subtract or add TLS_PRE_TCB_SIZE
	instead of sizeof (pthread_descr).
	(pthread_free): Add TLS_PRE_TCB_SIZE instead of sizeof (pthread_descr).
	* sysdeps/powerpc/tls.h (TLS_INIT_TCB_SIZE, TLS_TCB_SIZE): Define to 0.
