Unfortunately multiple directories have no defined semantic for other grub commands, so it does not look like the right place. May be consider something similar to how pkgdatadir is overridden at runtime. Something similar to

ln -s .../path-to-BIOS-build/grub-core i386-pc
ln -s .../path-to-EFI-build/grub-core x86_64-efi
pkglibdir=. grub-mkrescue ...

See grub-core/osdep/*/config.c.

It is better to send patches to grub-devel for wider review.

Users of grub-mkrescue can specify a directory to build a rescue cd from with -d.

If no -d is selected a rescue CD will be made with all the platforms a user has installed.

However currently if -d is specified more than once only the last -d parameter will be used when building the CD.

This is undesirable, for example if a user has built multiple versions of grub2 (e.g. one for EFI and one for x86) and has the modules in non-standard locations, grub-mkrescue should still function properly.

Attached is a patch which rectifies this behavior.
