Most profiles turn on xml2 by default so we can just have the xml global
use flag on by default to avoid most breakage. Then people turning -xml2
will just get xml until they switch to -xml. If you want to run a
minimal ship, you should be doing emerge -pv any way before updates to
check for new use flags.

betelgeuse@pena /usr/portage/profiles $ grep xml2 -r
/usr/portage/profiles/ -l

package.use is probably something we can't affect atm. It would probably
be useful if Portage checked for unexisting flags in it. This is just
one of those things that have to be properly informated to the user base
until our tools are better in handling these situations.
