Fix TestOperatorOverload for 32-bit builds

- use more goodies from Makefile.rules to correctly build a 32-bit
binary.
- avoid hardcoding typeof(nil) in the test.

This should partially fix the linux bot. There is still one assertion
failure remaining, which I'll have to investigate separately, as I am
not experiencing it locally.
