PYTHON_TARGETS is used only by a few packages, and not that popular ones  
at that (sorry, Michał! They're superb but still not widely known), so  
this variable doesn't implicate things much and default value could be  
tweaked in profile without much fuss and apprehension. If we find a  
sane'n'safe way to drop Python 3 from base system, that is. As far as I  
remember 3.2 was added to default PYTHON_TARGETS value exactly because of  
"stage3 has Python 3 by default".
