While disabling grafts does solve some of the issue, it's still not able
to cross-build everything and I didn't have time to look at it.

I could start the guix-daemon in darnassus for you to work on, by just
building guix as a user and using ./pre-inst-env, but I am afraid it
will create problems to darnassus. And Richard is using it for testing
things on the Hurd.

May I suggest giving you access to a local Hurd machine I have here so
you can hack as much as you want without worrying about side effects?
