It's possible to create multiple arch image, but it requires some

Why not just drop the -m32 and always build "native" images?  So if you
build the i386-efi target on i386, you get a 32-bit image and if you build
it on x86_64 you get a 64-bit one?

take the MacBook. There are different versions, let's call them (A), the original MacBook, 32-bit CPU; (B), mine, 64-bit CPU; and (C), Bean's, 64-bit CPU.

A and B require 32-bit EFI image. (actually, B might accept both 32 and 64 bits images, I'm not sure)
C requires 64-bit EFI image.

I can run a 32-bit distro and linux-kernel on any of them -- A, B or C. I can run a 64-bit distro on B or C.

Basically, neither CPU nor system arch tells you what kind of EFI image is "native". There must be some way to find out what kind of image *is* native -- but I have no idea what it is.
