Word of caution. ${prefix} also defines location of grub2 modules. So
you have to absolutely ensure that grub2 build in every OS is the same
as master. Otherwise you are risking running binaries from different
builds with undefined results.

I would rather use chain loading; you can directly load core.img using

chainload $prefix/i386-pc/core.img

(or x84_64-efi or rather exotic i386-efi)

which ensures your core.img and modules are consistent. There is no
blocklists involved, grub2 will read files so you are free to move
them around as you like.
