bug#41595: time-machine failure

During that interval, I see two potential culprits:

  01611d141e quirks: Add patch for <https://bugs.gnu.org/41214>.
  9db8836916 channels: 'build-from-source' restores '%guile-for-build'.

This is fixed by 36640207c9543e48cd6daa92930f023f80065a5d, which also
fixes the “incompatible bytecode” warnings.

That’s because the inferior for that commit is cached in
~/.cache/guix/inferiors.  That “hides” the problem.

Thanks, comrades!
