common subset of what --enable-debug and --enable-dbgutil do: enable 
various assertions, warnings, etc. (technically, both enable 
OSL_DEBUG_LEVEL > 0 and disable NDEBUG, for example)

what --enable-debug does in addition: settings that aid in step-through 
debugging (like -O0, -fno-inline)

what --enable-dbgutil does in addition: enable additional assertions, 
warnings, etc. that are binary incompatible
