Updating mrustc would be great, as an added bonus, the latest version
enables aarch64-linux support.  I just submitted a patch for it [0], it
would be great to pick it up when next updating rust.

I did also play with boostrapping directly from 1.54, instead of just
updating mrustc, but it's not building for me yet.  I'm attaching my WIP
patch in case somebody wants to take a look.  Specifically, it's failing
during the cargo build phase, so when testing it I recommend to run the
cargo build first to reproduce the issue.  I can post a log later, I
don't seem to find it just now :-).
