Looks fishy.  Especially you should note that 2.18.50 has
link_set_domains and sockindomain, which are both generated by the
DOMAIN_DEFINE(sockindomain); directive.

For some reason __start/stop_link_set is lost somewhere or not generated
at all.  If you have energy, you can try to track down where the behaviour
is different (compile/assemble/link).

But I still don't understand why the alternative networking domains
would work, since they do the same thing.
