There was one stray bit of code in virnetdev.c that required libnl to
build, but wasn't qualified by defined(WITH_LIBNL). Adding that, plus
putting a similar check around a static function only used by that
aforementioned code, makes libvirt build properly without libnl-devel
installed.

How useful it is in that state is a separate issue :-)
