Title: Enable custom optimization levels under superenv

I'm working through things that are known to require stdenv, and this seemed like the next easiest thing to tackle.

It would be nice if everything compiled with `-Os`, but I don't really like forcing stdenv just to work around that.

This is probably also more useful now that we allow custom GCC, and also for people using Homebrew to build custom packages.
