there is no directory build/grub2-2.04/build-i386-pc, but there is a build/grub2.204/grub-core, which I assume you meant. I tried with that directory, and indeed, the resulting image boots.

Thank you for your help so far! I'll reference this in the issue at https://bugs.busybox.net/show_bug.cgi?id=14281.
