> I think the bigger issue is that $BUILDDIR/gdb/data-directory overrides the standard data-directory. 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.

I see no reason to assume that we will not be able to reliably detect
a GDB build directory and to distinguish between that and other
projects.  Surely, we can find at least one or 2 files that only exist
in GDB.
