Oh, well, even better. I clearly don't know addr2line well enough, and
having a script that does this correctly automatically is clearly what
*I* need too.

Yeah, in practice the false duplicates almost never happen. We do have
duplicate function names, but they tend to be for simple things.

And the call trace often makes it obvious which particular function it
is for the human that is reading the output, but since it should be
easy to cut down on the potential duplicates, I think it's a good
thing to do.
