- Avoid the error message during linux system boot (boo#1184454)
- Prevent the build id being added to the binary. That can cause issues with the signature
Update to 15.4 (boo#1182057)
+ Rename the SBAT variable and fix the self-check of SBAT

Update to 15.3 for SBAT support (boo#1182057)
+ Drop gnu-efi from BuildRequires since upstream pull it into the
- Generate vender-specific SBAT metadata
