In the IRIX 6.5 machine I have access to, there's no such define among the
default headers.

Note that the failing curl test resolves a non-existing host name so it isn't
an ipv6 address and neither is ares_getnameinfo() used. libcurl still only
uses ares_gethostbyname().

I'll run some tests on the machine and see what I find.
