TEST_IPV6 is set to 'auto', though config.status.

On this platform (modern Linux, apparently just some system configuration
has IPv6 disabled) you cannot determine the absence of IPv6 at configure
time by looking at headers and library functions. It is a situation that
only becomes apparent while running the test.

What I do in this situation:
  1. Arrange the contents of the test in such a way that the mandatory
     stuff (IPv4) gets executed first; if it fails -> FAIL.
  2. Then comes the test of the optional features (IPv6). If it fails
     with a particular error indicating absence of IPv6 -> Either PASS
     or SKIP (as you like). If it fails in any other way -> FAIL.
