Bug #55545 IPv6 tests fail on HPUX

Description:
Several IPv6 tests fail on HPUX with the following symptoms:
---------------------------------------------------------
100723  6:32:13 [ERROR] Can't create IP socket: Protocol not supported
100723  6:32:13 [ERROR] Aborting
---------------------------------------------------------

This bug has been made out of Bug#54510.

As Daniel pointed out the reason for the failure is:
---------------------------------------------------------
The error is fairly straight forward, it's exactly what it says,
this box is not configured to support ipv6. The test case does
include the check_ipv6.inc file so that the test only runs when
ipv6 is available; the flaw in that logic is that there is
a mysqld option file for the ipv6 test that tells it to bind
to :: before that check can be executed. Since ipv6 is not
available, the address is invalid and so starting mysqld for
this test fails before the include file can be executed.
---------------------------------------------------------
