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