Why do we even consider a PE->ELF converter? I think the easier way to go would have the people building GRUB in cygwin (not exactly newbies) to have an i386-pc-elf "cross compiler" built first, then use that for the bootloader programs and the normal gcc for tools. Even a "naked" (i.e. libraryless) cross compiler would work, since the bootloader part of GRUB is does not need libs (in C terminology, it's "freestanding"). That way, we are free from "objcopy bugs" or "BFD design limitations".
This scheme is kinda like what's done with x86_64-pc-linux, with the difference that in that case we use the same gcc for both "host" and "target" by adding -m32 to the latter, but it's essentially the same concept. Habbit
