Why doesn=E2=80=99t it happen when doing: guix build grub-minimal -s i686-linux ? That=E2=80=99s because =E2=80=98as=E2=80=99 supports =E2=80=98.code64=E2= =80=99 there? > I am not sure if and how to report this upstream. Ideas for a bug > description? Apparently, non-cross builds "just" work (how?!). The issue seems to be that =E2=80=98.code64=E2=80=99 is not supported by cr= oss assemblers to 32-bit Intel, right? Is this a defect of cross-as in general, or a misconfiguration in our Guix package? Or is this normal behavior that should be fixed in GRUB? Anyway, the patch LGTM! Thanks, Ludo=E2=80=99.
