commit: https://git.buildroot.net/buildroot/commit/?id=9c52d4bee6c55ea13aeec8f013acdaeda8c9e519
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master
Mender-grubenv contains the boot scripts and tools used by Mender to
integrate with the Grub2 bootloader.
The user must select the following Grub modules for this package:
loadenv, hashsum, echo, halt, gcry_sha256, and test.
Because this patch also includes a grub version of fw_printenv and fw_setenv,
package/mender/Config.in must be changed as well at the same time, because if
both uboot-tools and this package are selected, during startup, mender calls
the uboot-tools version of fw_printenv and fails to start.

[Arnout:
- reorder depends clauses;
- add runtime tag to grub2 dependency
- remove wchar dependency from comment
- only error if BR_BUILDING
- use install instead of cp for a single file.]
