I am not sure it is simpler, because I don't think that the GDB binary
knows what the $BUILDDIR was. I am also wondering whether we might
activate the in-true use feature by accident too. I like the second
suggestion because it's very simple (as you could see from the patch),
and avoids touching the behavior in the installed-case. In other words,
our requirement does not affect the behavior at the end-user level.
