Makefile: Use cc-option to disable Qualcomm defined features
Browse files Browse the repository at this point in the history 
undefined-optimized and tautological and Qualcomm

cc-option instead of disabling directly. Without using
cc-options upsteam clang would complain about
undefined-optimized and tautological options.
