• I have read the contribution documentation for this project.
• I agree to follow the code of conduct that this project follows, as appropriate.
• The changes are appropriately documented (if applicable).
• The changes have sufficient test coverage (if applicable).
• The testsuite passes successfully on my local machine (if applicable).

Summarize your changes:
Some internal hooks are decorated with the __hookName field to indicate that the first parameter should be the task. However, when invoking these callbacks the config param was left out. This resulted in a signature mismatch, which caused issues like #3114 where the arch param was not being passed along correctly to rebuild.
