Use a flag to determine whether this macro should be set when intializing the preprocessor. This macro was added to the driver in 9d117e7b2a399a9b2bcf53fb9b9c0946e82dc75c because it can be conditionally disabled, but before that, the flag to gate behavior was removed under the assumption it wasn't conditional in b5b622a03c5136fa10d245dbe1f8f278ebd98d1b. This patch is to connect the macro with the preexisting flag
