There should be a SHA here. "not available" indicates that you didn't compile
from the git repository directly, and now I do not know how old this compliance
test is. Always compile from the latest git repo, never use a version from e.g.
a distro as they tend to be old and missing tests.

It would be great if you can do this and reply with the new compliance output.

Thanks!
