- Non-cross stdenvs are honest and assert that `crossSystem` is null - `crossSystem` is a mandatory argument to top-level/stage.nix, just like `system` and `platform` - Broken default arguments on stdenvs for testing are gone. - All stdenvs (but little-used stdenvNix) take the same arguments for easy testing.
