Subject: [PATCH 03/17] Introduce "--enable-ipv6" ./configure option

I think we want to continue to allow nfs-utils to be built on systems that
do not have any IPv6 development libraries and headers installed, so add a
./configure switch that allows distros to disable IPv6 functionality.

For now, it defaults to "yes" and is a no-op. As we add IPv6 functionality
we can insert it behind this option.
