It would be great to do that at least temporarily on master. It will
not affect much since other architectures are bootstrapped already. We
could also make it conditional. Reproducibility instructions will have
to contain exact commit id and configuration for both GNU Guix System
(x86_64-linux) and GNU Guix which can cross-compile.
