Hello! I ran `guix system reconfigure /etc/config.scm` and now rust is compiling. Rust is compiling too long.

I've produced `guix graph --type=reverse-package rust | dot -Tsvg > r.svg` to see why does guix do this, but there is no answer.

My config and rust reverse dependecies tree are in attach.
A tree has only one node - rust.
