It appears that this is due to there not being a globally scoped, 
non-loopback ipv6 address configured. In this case the appropriate 
behaviour for getaddrinfo when AI_ADDRCONFIG is specified in the hints 
is to return the error above.

I guess there must have been some change recently in glibc to discard 
the loopback address (or link scoped addresses?), given that this has 
worked for me with the same configuration on older versions.

Andrew has checked in a fix to the test script that skips the test in 
this case to avoid an error.
