.gitignore is insufficient

[mjlosch]

I find that I need to add "build" and "run" to .gitignore in order to avoid having my screen cluttered with links from the build and run directories in verification after having run ./testreport. Can git differentiate between links and real files? What would be the best syntax for excluding links in .gitignore? I couldn't find anything on the web.
I have been told that the testreport suite does "in-place-building" or similar and that that's not the best idea, but I don't think we want to go away from that, do we? We could rename all build and run directories into _build and _run, couldn't we?
Is there a better solution?

It's possible to put .gitignore files in subdirectories, so each test directory could get its own with build and run listed. This should deal with the clutter.

Changing the directory names would also fix that, but might be more of a pain for users?

I'm not sure about how to exclude links. Will have to look into it.
