If I don't use `add_libfuzzer_test()` for the unit test then I will have duplicate the logic that fixes the weak linking issue for the unit test which isn't desirable because I am trying to avoid as much boiler plate CMake code as possible.

Yes, I hope to not need CustomMainTests in future you can safely delete that part. 

Sure, please have as much code reuse as possible for gnuint test, but I think you can do it w/o thie NO_MAIN
