Change the cmake variable COMPILER_RT_CAN_EXECUTE_TESTS to be an option so that it can overwritten.
Change the cmake variable COMPILER_RT_CAN_EXECUTE_TESTS to be an option so that it can overwritten.

The reason why this simple change is needed is that I am trying to set up a

The default behavior follows exactly what was there before implying that no ones
builds should be affected at all.
