This looks a little broken behaviour to me. My guess is that it
returns an AF_INET6 socket but doesn't support it in the kernel.
In that case with the AI_ADDRCONFIG option it shouldn't have
returned that address. The question is wether your getaddrinfo()
supports that option, and wether it's working or not.
We can fix this by going over all the returned addresses until
one of the socket() calls works.
We probably should also skip AF_UNIX sockets, since that might
not be want we want.

That is just evil. It can't even resolv localhost? Do you have
a localhost entry in /etc/hosts?
If that's not the problem I see no other way but to use
INADDR_LOOPBACK and in6addr_loopback directly instead, which I
really hate.

The ai_family should be either AF_INET or AF_INET6, ai_socktype
should be SOCK_DGRAM, and ai_protocol 0 or IPPROTO_UDP.
