lynx-dev one more IPv6 fix for lynx2.8.4dev10

[sumikawa]

Hi,

The follwoing patch is one more IPv6 fix for lynx2.8.4dev10.

Configure fails when configure is run with --enable-ipv6 on IPv4-only
kernel which has getaddrinfo() because current getaddrinfo checiking
is too strict.

Needless to say, you should run autoconf after applying the patch.
