The configure checks are supposed to check for features and functions, not for
specific platforms or operating systems. Thus, a check like this would need to
check for a defective getaddrinfo() (if at all possible).

Are we sure this is really an OS flaw and not just a config or site specific
problem of yours?

Finally, the ipv6 support enables ipv6 so it isn't just slower than the
regular name lookup, it offers additional features.
