commit 64d1e08ea822bf47cb2796ad0f727136227f983c
Author: Andreas Schwab <schwab@suse.de>
Date: Mon Oct 2 14:30:46 2017 +0200
Move nss_compat from nis to nss subdir and install it unconditionally
This has been tested that local lookup still works with and
without an installed libnss_nis, and that NIS lookup works when
libnss_nis is available.
