This is defined nowhere and each configure now gives me anthe following error:

  ./configure: line 75099: LIBVIRT_GETTEXT: command not found

It does not fail the configure, however, so the build continues and that's
probably why nobody noticed.  I'm not sure what this was supposed to do, but I'm
not sure if we just want to remove it, so that's why I'm replying here.
