If we detect run-from-builddir based on the presence of other files/directories, and some other application happens to use the same files/directories, then the user is basically stuck with either a non-working gdb (sans -data-directory) or having to uninstall that other application.

But we have to make assumptions about other applications that are not under our control, that they do not use the same files, which I think is an assumption that we should avoid if possible (who knows what's out there). Of course, we can greatly minimize the risk by checking for more files and/or the contents of files. But it is possible to avoid this assumption, e.g., the other two solutions in my previous email, hence my preferences.
