cc/config: do not generate additional debug info for AFDO

We do not generate our own AFDO profiles for many reasons, not limited
to but including:
 - ETM-capable device access
 - Custom rolled fixes in upstream profiles

As such, we do not need to generate additional debug info. Removing this
decreases output binary size and saves on compile time.
