ntpdate has been updated since 4.2.0, and now walks the list of returned
addresses. It doesn't use AI_ADDRCONFIG but does call isc_net_probeipv6()
to see if IPv6 is available, which might amount to the same thing.
Also the method used to compare IPv6 addresses in findserver() has been
changed, which fixes the problem mentioned above.
