Please wrap line.

Please align ‘else’ branch with ‘then’ branch:

  (if hurd
      consequent
      alternate)

Ditto.

As I suggested to Manolis, could you make sure that this doesn’t break
the existing GNU/Linux cross-toolchains?

Namely, could you run:

  guix build -e '(@ (gnu packages cross-base) xgcc-armhf)'

If that passes, OK to push to wip-hurd.

Thank you!
