I have a number! I just pushed a couple of patches to staging to fix the
bootstrap on aarch64, and to decrease the build time and resource usage,
and the numbers are in!
https://ci.guix.gnu.org/build/1632586/details
11863 seconds from downloading mrustc to building rust-1.60, for 198
minutes, or 3.3 hours.
