[PATCH 2/5] configure.ac: Don't check for AI_ADDRCONFIG

[Chuck Lever <chuck.lever@oracle.com>]

Commit 1ea2c3be: "nfs-utils: Remove all uses of AI_ADDRCONFIG,"
(October 28, 2010) removed the last use of AI_ADDRCONFIG.  Even so,
ipv6.m4 uses this check to ensure that the local getaddrinfo(3)
implementation is recent.  Maybe we shouldn't bother.
