SELinux detection on GNU/Hurd..

[Alfred M. Szmidt]

Ulrich, Roland, what do you consider about disabling the SELinux
detection warning on both GNU/Hurd and GNU/Linux?  Patch applied.

Another solution is to just enable the check only for GNU/Linux, but
that is obviously stupid for various reasons since GNU/Hurd might get
SELinux support (unlikly, but a possibility).

checking for is_selinux_enabled in -lselinux... no
