c2b3e370d6 - apply hunk that fixes an issue with (wrong?) dependencies. Initial notes were:
There is something wrong in the new buildsys: If one selects ip and has e.g.
  rule or route unset, ip still wants to build those.
  This fails (correctly) since rtnl_rttable_n2a and rtnl_rtrealm_n2a aren't
  available if they were turned off. TODO: Talk to vda about this
