It's this last step which is of interest afaict; how you configure
things does not seem to matter. The dist target implies building
dist-tools, which in turn has install-tools as a dependency. Most
of the sub-directories under tools/tests/ have an empty
install target in their makefiles though, which means nothing is
going to be done when entering the respective directories.

I can't spot any relevant difference between the versions you
mention (or master). I'm afraid you'll need to dig a little deeper
yourself (unless someone else has an idea).
