Partial backport of:
commit 17c199ee92e4ca8a34a47c42924608a25a444eb2
Author: Joseph Myers <joseph@codesourcery.com>
Date: Wed Jun 17 20:08:22 2015 +0000
Fix gethostbyaddr in6addr_any, in6addr_loopback namespace (bug 18532).
The conform/Makefile changes have been omitted because glibc 2.17 did
not have linknamespace tests.
