  The local path, used in standalone builds, is preferred. If it is not present
  but the external path is, the external path will be used. If neither path is
  present, the local path will be used, so that error messages uniformly refer
  to the local path.

  Args:
    local_path: The preferred local path to use for a standalone build.
    external_path: The external path to fall back to.

  Returns:
    A 2-tuple. The first element is 'standalone' or 'external', depending on
    whether local_path or external_path was chosen. The second element is the
    chosen path.
