Update.

	* sysdeps/unix/sysv/linux/getdents.c (__getdents): The Linux
	kernel does not allow relative seeks on descriptors associated
	with directories.  Go back to get the position in the directory
	every time we enter the function.  Return -1 and set errno if one
	entry could be read from the kernel but does not fit into the
	buffer passed in by the user.
