 Or let the default be empty, and choose a default from the .mk file when it's
empty. But we've discussed that before and some people didn't like it.

 Note: this applies for all string options for which we have multiple defaults:
BR2_TARGET_GRUB2_BUILTIN_MODULES, BR2_TARGET_ROOTFS_ISO9660_BOOT_MENU.
