--stable-ids is generally meant to be used by different versions of the same

name references to match the package that resources are being generated for.
Note: This will fail if the package ID of the resources in
|options.use_resource_ids_path| does not match the package ID of the
resources being linked.
Args:
options: The command-line options
Yields:
Path to the transformed resource IDs file (lines formatted like
