There hasn't been much development in the mrustc repo for the past few
months and I believe the issues blocking i686 (needs too much memory at
once) is still present. As far as powerpc64le, it does pretty well with
mrustc but doesn't get through the whole bootstrap yet.

Another option would be to work on the cross-compiling ability of the
cargo-build-system, then you could at least cross compile to them.

I will point out that s390x and mips aren't actually supported in Guix

Speak in the plural and no one will realize it's a team of one ;)

I'm thinking of tagging the rust stuff with [rust team] so it stands out
and is easily searchable. if/when I send patches for other teams I'll
probably tag those too and hope it catches on.
