Does p2v/virt-p2v (binary) exist?

The error seems to be libxml2 missing.  Now it builds OK using just a
plain build, but not from makepkg.

Can you get makepkg to add `V=1' flag to make, ie:

  make V=1

That should print the full compile/link commands.

I'll see if I can build it on my ArchLinux VM.
