	sysdeps/unix/x86_64: sysdep.S 

Log message:
	2002-09-29  Roland McGrath  <roland@redhat.com>
	
	* sysdeps/unix/sysv/linux/x86_64/sysdep.S [USE_TLS && HAVE___THREAD]:
	Define errno in .tbss.
	* sysdeps/unix/x86_64/sysdep.S [USE_TLS && HAVE___THREAD]: Use TLS
	access for setting errno.
	* sysdeps/unix/x86_64/sysdep.S: Store 32 bits at errno, not 64 bits.
	AFAICT, it was just blind luck that the word following errno in .bss
	was just alignment padding and not some other variable to be clobbered.
