Update.
* sysdeps/unix/sysv/linux/Makefile (sysdep_routines): Add
libc_multiple_threads.
* sysdeps/unix/sysv/linux/libc_pthread_init.c: Move definition of
__libc_multiple_threads to...

* sysdeps/unix/sysv/linux/x86_64/sem_post.S: Remove unnecessary
versioning.
* sysdeps/unix/sysv/linux/x86_64/sem_trywait.S: Likewise.

* sysdeps/unix/sysv/linux/x86_64/pthread_once.S
(__pthread_once_internal): Define.
* sysdeps/unix/sysv/linux/i386/i486/sem_post.S: Use shlib-compat.h
macros instead of .symver directly.
* sysdeps/unix/sysv/linux/i386/i486/sem_trywait.S: Likewise.
* sysdeps/unix/sysv/linux/i386/i486/sem_wait.S: Likewise.
