Hey,
When attempting to guix pull using the aarch64-linux system, I'm seeing
some issues with derivation outputs. I tried with a newer and older
commit, and the result is the same.

The problem here is that we’re building the trampoline,
“compute-guix-derivation”, for AArch64. It builds if substitutes are
available (likely) and fails to build otherwise. And then we try to
execute it locally, and since your machine is not AArch64, it fails.
The first patch attached does what I thought was all it would take to
fix it. But then I realized that the second patch is needed so that
‘make-config.scm’ uses a Guile for the right system, same for
“module-import.drv” and so on.
Together, these two patches solve the problem (not retroactively
though), but we need to check the implications of changing the default
value of #:guile-for-build.
Thanks,
Ludo’.

Subject: [PATCH 1/2] build-self: Always build the trampoline for the current
system.
Previously we'd build 'compute-guix-derivation' for the target system.
Running it would then fail (unless qemu-binfmt support was set up or
something similar).
Fixes <https://bugs.gnu.org/39531>.
Reported by Christopher Baines <mail@cbaines.net>.

Until now, the default #:guile-for-build would be Guile lowered to
whichever system was current when %GUILE-FOR-BUILD was set. This would
break when passing #:system to a value other than %CURRENT-SYSTEM.

Hey,
Thanks for investigating :) I completely forget why I encountered this,
but it was probably around getting the channel instance derivations in
to the Guix Data Service, but I think I got that working, so I guess I
somehow avoided this issue.
Thanks,
Chris
