Comment:
The upstream binary would be used to cross compile (and it sounds like that's supported by passing `--platform` to the `rpython` script) for all target platforms. `pypy-bootstrap` (or whatever you want to call it) would only need to support x86_64 and i686 for it to then be possible to use it to cross compile for all architectures, right?
