bug#45654: Building guile on x86_64 for aarch64 fails because of a missing guile

[Stefan]

Hi!

I setup my virtual x86_64 system with an qemu-binfmt-service-type for aarch64 
and tried to build guix for aarch64. But this failed because of a missing guile:

stefan@guix ~$ guix build -s aarch64-linux guix@1.2.0-8.7624ebb
Folgende Ableitung wird erstellt:

I did a guix gc and then tried to build guile itself. But again it failed to 
build because it is missing guile itself.

stefan@guix ~$ guix build --check --no-grafts --system=aarch64-linux guile@3.0.2

Then I thought to try to download the referred but missing guile:

stefan@guix ~$ guix download

Afterwards building guix for aarch64 was possible.
