This patch just displays a better message than the default stack trace
but dose not try to fix the problem. A further patch will be created but
it effects versioneer so may take longer to land as it may need to go
via versioneer mainline.

This has been done in a way that I hope might be able to be upstreamed
in to versioneer. This is not garanteed but it would be good if it
could be.

Please see https://github.com/warner/python-versioneer/pull/186 and

When GDB looks for debug symbols it looks for the full path of the file
inside the configured debug-file-directory. For example, if the
debug-file-directory is set to a default of /usr/lib/debug, and you are
debugging /usr/bin/python3, GDB will look for its debug symbols at this
location: /usr/lib/debug/usr/bin/python3.

BuildStream has been putting all debug files inside /usr/lib/debug
under their $(basename), so in the above example GDB would fail to find
any debug symbols for /usr/bin/python3 because they would be in the
incorrect locatoin of /usr/lib/debug/python3.
