Sorry this one fell through the cracks Sam, the patch looks reasonable
to me, so long as we still are providing the strip commands (I think
there is another issue about this being very GNU/Linux specific).

As a side note, there is also a plan to expose the sources at the paths
they were built from as an option in the `bst shell`, with the goal of
providing better context for debugging too:

This will surely materialize in the coming cycle.
