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

12c96a64a4 - set the scope properly. Thanks to Jean Wolter, who wrote:
busybox ip and the original ip utility behave differently when setting
the following route (verified with ip route show using the original ip
utility):

   ip route add 10.0.0.138 dev eth0

Result for busybox ip:

       # ip route add 10.0.0.138 dev eth0
       # /usr/local/bin/ip route show
       10.0.0.138 dev eth0

Result for ip:

       # /usr/local/bin/ip route add 10.0.0.138 dev eth0
       #  /usr/local/bin/ip route show
       10.0.0.138 dev eth0  scope link

A following "ip route add default via 10.0.0.138" fails for busybox
ip, since the kernel can not find a route to 10.0.0.138 (it replies
with Network is unreachable).

The reasons seems to be that the original ip utility explicitly sets
the scope after parsing all parameters. This is missing in busybox,
the attached patch fixes this. I took this from the original iproute
sources and removed some variables, which are not needed for busybox.
