Leah Rowe 2e38ddaa9b Revert "Remove most of Ferass's lbmk contributions"
This reverts commit a4ea286731.

The licensing audit has been abandoned. I will not be re-licensing
in bulk to MIT.

I can still use MIT license on new works, e.g. utilities, but there's
really no pressing need to re-license lbmk. It's just shell scripts,
and most of what it interacts with (coreboot, grub, seabios) is GPL
anyway.

So who cares?

Ferass's patch was removed due to refusal to re-license, but the
decision to re-license has been canceled.

I'm now aiming for a quick stable release.
