Well, if we don't store that value yet, we probably should.

What I have in mind is a scenario of a user stuck at a particular OS
version who upgrades MacPorts and the new version of MP makes sure
that that variable is stored. Then the user decides to switch to
libc++. It would be awesome if this process was fully automated and
the ports would all be reinstalled automatically. (But don't ask me
for links to line numbers, I'm not familiar with the core code well
