John Ericson d240a0da1a top-level: Remove cycles: stdenv calls in top-level but not vice versa ... This commit changes the dependencies of stdenv, and clean-up the stdenv story by removing the `defaultStdenv` attribute as well as the `bootStdenv` parameter. Before, the final bootstrapping stage's stdenv was provided by all-packages, which was iterating multiple times over the top-level/default.nix expression, and non-final bootstrapping stages' stdenvs were explicitly specified with the `bootStdenv` parameter. Now, all stages' stdenvs are specified with the `stdenv` parameter. For non-final bootstrapping stages, this is a small change---basically just rename the parameter. For the final stage, top-level/default.nix takes the chosen stdenv and makes the final stage with it. `allPackages` is used to make all bootstrapping stages, final and non-final alike. It's basically the expression of `stage.nix` (along with a few partially-applied default arguments) Note, the make-bootstrap-tools scripts are temporarily broken		2016-11-30 19:10:59 -05:00
