fix(pie): pass -fpie to the preprocessor as well

Browse source 
When PIE is enabled, the `-fpie` flag is passed to the compiler but not
to the preprocessor. This change ensures that both tools are aware of
when the image is position-independent when preprocessing, which impacts
some pre-defined preprocessor definitions.
