Changing the binary used at compile time is really not a good idea,
because libvirt uses netcat on the remote machine, which is not
required to be the same distro as the client machine on whihc you
built libvirt. So by making socat vs netcat a compile time option
you pretty much guarentee incompatibility between libvirt client & 
server betweeen distros. It is really better to fix netcat on the
distros where -U isn't available.
