Dont bypass compiler driver for Dependency generation options

We can let compiler driver pass the right options to preprocessor after
processing -Mxy options, right now its bypassing the gcc driver and
handing them straight to cpp

This also helps in other compilers processing these options correctly
for their preprocessors consumption
