Good suggestion to update the BUILD_NUMBER.

For my part, it works to use b00 in my dev work, and that bypasses
the version check, but I agree that is not desirable for general usage.

The question is, when should the number be updated, and what should
the build number show as, when building an otherwise untagged tip
of the jtreg repo?

For the cloudbees set up, I was suggesting to use a build number
derived from the latest jtreg tag (for a tagged build) or b00 for a
build of tip.   I'm open to other general suggestions for good
practice, here.
