When I build multiple targets (e.g. via a group or explicitly) it's not often clear which target a build(ing) stage corresponds to [sample log](https://gist.github.com/ciaranmcnulty/ad664329a303ed85d73d4f48735db884) [Dockerfile](https://github.com/ciaranmcnulty/phpqa/blob/535fe6f857d4b774dc34b9f15d378d0043e2c9c8/Dockerfile) The build steps that don't have a TARGET name are the ones that do `COPY --link`, but not all of the them are missing it. I'm not clear what is happening behind the scenes to cause this!
