Update Makefile Phonies
# What does this PR do?
This PR fixes vestiges of previously existing targets in the Makefile, and potentially adds missing entries as well.

Please let me know if any other recipes are to be added? My understanding is that we want to force the invokation of the recipe even if the file with same name exists, based on [this](https://www.gnu.org/software/make/manual/html_node/Phony-Targets.html#:~:text=A%20phony%20target%20is%20one,name%2C%20and%20to%20improve%20performance). Please correct me if I'm wrong.
