The standard way to do this is to have a command line argument named
BOOT_IMAGE (as in BOOT_IMAGE=/foo/bar/baz). There is no reason to do
this differently from every other bootloader.
Why build the real-mode code as part of the kernel binary? If you have
to reference kernel symbols, you can do that with the -R option to ld.
Bundling it into the kernel binary just to then extract it later is
silly at best.

This doesn't exactly fit very well the standard pattern. Something like
make gujin TARGET=... would be more like it.
Given how many of your files are highly Gujin-specific, and have generic
names, please put them in a subdirectory (e.g. arch/i386/boot/gujin/).
