 From 'man gcc', in the section called "Intel 386 and AMD x86-64 Options":

"-march=cpu-type
            Generate instructions for the machine type cpu-type.  The 
choices for cpu-type are the same as for -mtune.  Moreover, specifying
            -march=cpu-type implies -mtune=cpu-type."

So, in your example above, -mtune is unnecessary.
