1.93.0

I'm publishing the artifacts on github releases and on a partial mirror on http://tcz.facedebouc.sbs/.

Details

The docker image which built this can be found here
Note that it is big. Once pulled and uncompressed, it can take 40 GB or more.
I included the interesting files (build-log.txt, bootstrap.toml) in this release.

rust-x.y.z-i586-unknown-linux-gnu.tar.gz contains the toolchain which can run
on an i686 CPU.

Technically, it should be running on an i586, but see the
README for the rust-i586 repository
which explains why it may not be possible.

I'm using it for retro-computing in the rust-i586 git repo
and with a ThinkPad 560z. There, I build the .tcz files that can be used
with Tiny Core Linux to load rust and use it.

The artifacts at http://tcz.facedebouc.sbs/artifacts/artifacts.html might not always download

The artifacts at http://tcz.facedebouc.sbs/artifacts/artifacts.html
can be downloaded with a script at http://tcz.facedebouc.sbs/navigate.sh.
They may not always download because of limitations
Here's a copy of the navigate.sh script:
