As Skara doesn't manage versions of jtreg (it lacks a version configured in `.jcheck/conf`) a back port request seems not required.

The warning only addresses a naming conflict detected for my personal fork - which I tend to ignore, as I won't sync that branch in the future.

In the light of that, I will issue a `/integrate` command in a follow-up comment.
