Applied to `rust-next`. I added Boqun's fix for `rusttest` as well as
a fix for `rustdoc` (which requires a conditional for host crates like
`macros`); and added a couple `Links` to the arm64 discussions.

I would appreciate extra testing for this one (please use `rust-next`
commits in that case).

Thanks everyone!

Cheers,
Miguel
