(libc: GLIBC_2.0) [USE_TLS && HAVE___THREAD]: Remove _errno, errno.
	(libc: GLIBC_2.3) [USE_TLS && HAVE___THREAD]: Put errno here instead.
	* resolv/Versions: Use %include <tls.h> to get USE_TLS defined.
	(libc: GLIBC_2.0) [USE_TLS && HAVE___THREAD]: Remove _h_errno, h_errno,
	and _res.
	(libc: GLIBC_2.3) [USE_TLS && HAVE___THREAD]: Put h_errno, _res here.

	* elf/tls-macros.h [__x86_64__] (TLS_LE, TLS_IE, TLS_LD, TLS_GD):
	New macros for x86-64.

	* sysdeps/unix/sysv/linux/alpha/bits/time.h: File removed.
	It was indentical to the linux/bits/time.h file.

	* nscd/nscd_gethst_r.c (nscd_gethst_r): Add a cast to silence warning.
