	* sysdeps/unix/sysv/linux/futimesat.c (futimesat): If FILE is NULL,
	set access and modification times of the file referenced by FD.
	* sysdeps/generic/futimesat.c (futimesat): Don't return EINVAL if
	FILE is NULL.  Don't check FD if FILE is absolute path.

	* nscd/nscd_gethst_r.c (nscd_gethst_r): Avoid unnecesary read call
	if there are no aliases.

	CFLAGS-pwdcache.c, CFLAGS-grpcache.c, CFLAGS-hstcache.c,
	CFLAGS-aicache.c, CFLAGS-initgrcache.c): Add -DHAVE_SENDFILE.
	* sysdeps/unix/sysv/linux/kernel-features.h (__ASSUME_SENDFILE):
