+- Make the default stage for x.py configurable [#76625](https://github.com/rust-lang/rust/pull/76625). This can be enabled with `build-stage = N`, `doc-stage = N`, etc.

 - Add sample defaults for x.py [#76628](https://github.com/rust-lang/rust/pull/76628)
 - Add `--keep-stage-std`, which behaves like `keep-stage` but allows the stage
