The "seabios" word in the commands refers to whichever directory the
seabios project has been cloned / checked out / extracted, doesn't it?
For a second the cp command looked as if I should be able to find a
seabios subdir (beside the roms subdir) in qemu. What about

> +	cp roms/config.seabios $SEABIOS_DIR/.config

> +	make -C $SEABIOS_DIR olddefconfig

(BTW, good to know! :))
