Goal: 

The shim project depends on gnu-efi but doesn't really use much of it and the stuff that are used can be implemented as a minimal C runtime for UEFI.

A work-in-progress for that can be found at: https://github.com/vathpela/crte

Acceptance Criteria

A list of verification conditions, successful functional tests, or expected outcomes in order to declare this story/task successfully completed.

• Verify that shim builds and works correctly when using with crte instead of gnu-efi as dependency.
