handle stage0 cargo and rustc separately

Browse Source 
This change allows setting either `build.cargo` or `build.rustc` without requiring
both to be set simultaneously, which was not possible previously.

To try it, set `build.rustc` without setting `build.cargo`, and try to bootstrap on clean build.
