Ensure that parallel parsing sbs calls pass on --no-depend-generate and --no-depend-include (as these influence makefile generation).
Make .DEFAULT a double-colon target, so we don't have to worry about duplicate instances due to -include.
Code review updates.
List of deprecated/unsupported scripts:
- get_languagepack_id.py (old process)
- generate_tutorial_content_conf.py (need a requirement for that)
- create_version.py (migrated it as an iMaker feature)
- createlocales.py make template should now use iMaker feature to generate the languagepack
- create_version.py make template should now use iMaker feature that handle version string generation
