Interesting. Why doesn’t it happen when doing:
guix build grub-minimal -s i686-linux
? That’s because ‘as’ supports ‘.code64’ there?

The issue seems to be that ‘.code64’ is not supported by cross
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’.
