Now lets move this idea to GRUB 2:

There is a build server is running on PPC/Linux and it wants to build
all architectures supported by GRUB 2 (provide proper boot code for all
arch and tools) and then makes software bundles (rpm,deb, or so) for all
architectures.

In example if all shell tools are to be ran on x86-64/Linux and then
boot code needs to be compatible with x86-32 as there is PC-BIOS present
on target system.
