libuv 1.0.0: tests fail if ipv6 is missing

[jbergstroem]

I still get a lot of fails when disabling ipv6 in my linux kernel (3.17.2). Shouldn't these really be skips?

I guess another way of approaching this would be checking for ipv6 support through autoconf and just not build/run these tests?

A patch for skipping tests in absence of IPv6 support at runtime would be welcome, indeed. Please reopen this issue on https://github.com/libuv/libuv, as development has moved there now.
