	[BZ #737]
	* sysdeps/unix/sysv/linux/i386/i486/sem_trywait.S (__new_sem_trywait):
	Use direct %gs segment access or, if NO_TLS_DIRECT_SEG_REFS,
	at least gotntpoff relocation and addition.
	* sysdeps/unix/sysv/linux/i386/i486/sem_timedwait.S (sem_timedwait):
	Likewise.
	* sysdeps/unix/sysv/linux/i386/i486/sem_post.S (__new_sem_post):
	Likewise.
	* sysdeps/unix/sysv/linux/i386/i486/sem_wait.S (__new_sem_wait):
	Likewise.
