Small systems can use ioctl/ifconfig for routing and
interface configuration. Make rtnetlink optional
This saves ~29k without LTO, more with LTO.

Andi, I've had about enough with this patch series.

We have moved several tools to only use netlink because it's
the only extensible facility, and we are not looking back.

The moment one of these "small" systems, or whatever you want to call
it, tries to use any feature added to device configuration in the last
20 years ioctl doesn't cut it.
