I don't see why you're still using these defines. It's unlikely that this code
will work if NETLINK_ROUTE is defined but RTMGRP_IPV4_IFADDR isn't, for example.

If there are versions of the netlink headers that don't have all of them it
may be possible to work around that (e.g. by defining them ourselves), if not
we can expand the configure check.
