x.py install is a bit of a mess I guess between paths and aliases. My tendency is to move towards the dist tarball names for simplicity (and maybe just universally support any of them; I suspect it might not be that hard with the relatively uniform tarball generation work @pietroalbini did a while back).

Can be a future PR.

Yeah, my impression is that x.py install isn't a super well trodden path in general - not sure who's using it. I can look into cleaning it up sometime in the next few weeks, I've been meaning to write up instructions for how to port a new architecture anyway and I suspect this will come up as part of the work. Leaving it be for now.

let tarball = builder.ensure(dist::Rustc {
compiler: builder.compiler(builder.top_stage, self.target),
});
