	* sysdeps/unix/sysv/linux/i386/clone.S: Add support for NPTL where
	the PID is stored at userlevel and needs to be reset when CLONE_THREAD
	is not used.
	* sysdeps/unix/sysv/linux/86_64/clone.S: Likewise.

	* sysdeps/unix/sysv/linux/arm/clone.S: Update uses of RETINSTR.
	* sysdeps/unix/sysv/linux/arm/mmap.S: Likewise.
	* sysdeps/unix/sysv/linux/arm/mmap64.S: Likewise.
	* sysdeps/unix/sysv/linux/arm/socket.S: Likewise.
	* sysdeps/unix/sysv/linux/arm/sysdep.h: Likewise.
	* sysdeps/unix/sysv/linux/arm/vfork.S: Likewise.
