Well, yes, it's not pretty, but I lack ideas for a clear improvement.

Yes, and not just here. Any test that can be run directly in the build
tree would imo better have such a target, so re-building and running
it can be invoked with a single make invocation. Having to re-build
the entire tools/ in order to then (re-)run one of these tests is, in
particular, way too much latency.
