Let's suppose that $PV is "2.5.1". How would I get the "2.5" in it in an
ebuild? I know about ${PV:0:3}, but this breaks if $PV is, say,
"2.13.1". In that case, I would get "2.1" instead of "2.13".
I've looked in the various eclasses if there's some utility function
that get me the major and minor version, but can't find anything.
