How exactly is process_options rerun?  It's a static function in toplev.c, 
called once from another static function in toplev.c....  I guess maybe 
you mean decode_options.  In that case, maybe you need to implement 
TARGET_OVERRIDE_OPTIONS_AFTER_CHANGE to set at least some of the variables 
set by darwin_override_options.
