Heh.

Ok, we don't want to *just* have the "./" pattern ever be replaced,
because for all I know there could be a directory name ending with "."
in there somewhere.

But I guess we could do it this way instead:

  --- a/scripts/faddr2line
  +++ b/scripts/faddr2line
  @@ -79,7 +79,7 @@ find_dir_prefix() {
                  return
          fi

  -       DIR_PREFIX=$prefix
  +       DIR_PREFIX="$prefix\(\./\)*"
          return 0
   }

and thus just make it part of the auto-generated pattern string instead.
