I do not recommend setting options this way, especially -mcx16 -msahf and others may produce code that does not run correctly on all systems.

I recommend using
    CFLAGS='-g -O2 -Wall -march=native' CXXFLAGS='-g -O2 -Wall -march=native'
to get the best performance since it turns on all possible processor features like mcx16 if and only if the used system supports it.
