i removed this before, when making grub multi-tree, because the design i used in an earlier version of the patch actually added the grub.elf generation to grub source itself, but then i decided to hack around the grub build system from lbmk/cbmk instead re-add this functionality, so that users can easily insert their own custom grub.cfg into cbfs without needing to re-build their image.
