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.
