Yes, for the emulator test harness, which can be built both 32-bit and 64-bit (like all of the tool stack can be). When the tool stack is otherwise 64-bit we even have Makefile logic there so the test harness can be built both ways in parallel (and hence things can be tested both ways, provided 32-bit runtime packages are installed).
