Hey Ludo,

> Could you boil the problem down to a “guix build --target” command?

No, but I just found a small reproducer:

--8<---------------cut here---------------start------------->8---
(use-modules (gnu)
             (gnu packages gtk)
             (guix)
             (guix store))

(run-with-store (open-connection)
  (mlet* %store-monad ((target (set-current-target "aarch64-linux-gnu"))
                       (drv (lower-object
                             (computed-file "test"
                                            #~(begin
                                                (mkdir #$output)
                                                #+guile-rsvg))))
                       (out -> (derivation->output-path drv)))
    (mbegin %store-monad
      (built-derivations (list drv))
      (return out))))
--8<---------------cut here---------------end--------------->8---

This should fail with:

--8<---------------cut here---------------start------------->8---
In guix/packages.scm:
  1072:16  5 (package-derivation _ #<package guile-rsvg <at> 2.18.1-0.05…> …)

  1260:45  2 (fold-bag-dependencies #<procedure 7f484b8bd5e0 at gui…> …)
  1072:16  1 (package->bag _ _ _ #:graft? _)
  1183:21  0 (thunk)

guix/packages.scm:1183:21: In procedure thunk:
ERROR:

Thanks,

Mathieu
