Makefile: Use cc-option to disable Qualcomm defined features

undefined-optimized and tautological and Qualcomm
defined features. To disable these compiler options use
cc-option instead of disabling directly. Without using
cc-options upsteam clang would complain about
undefined-optimized and tautological options.
