The problem is not limited to linux-libre.  Many important builds are
failing in the same way, including the 'guix' package:

  https://hydra.gnu.org/build/2071169
  https://hydra.gnu.org/build/2044402

I would say that Hydra is mostly broken right now.  This might be
related to the recent switch on Hydra to guix-based-on-guile-2.2.
