I ran into the same problem while porting GuixSD to MIPS, before I had
GRUB working.
The problem here is that the method for copying the necessary store
items to the target directory is to copy grub.cfg and its transitive
closure, using (maybe-copy grub.cfg).
However, if --no-grub is specified, then grub.cfg is not built.
The preliminary approach I used successfully was to build and install
grub.cfg even if --no-grub is specified, although 'grub-install' is not
run in that case. Here's the patch I used:
