If you set CPUTYPE, -march is set to match, so setting -march=native
should be redundant. OTOH a number of other make variables are defined
from CPUTYPE, so if you set  -march=native, but not CPUTYPE you might
miss some optimisations based on build options. 

I've no idea whether there are any such options, just that you're
probably not going to do better than setting CPUTYPE, and leaving the
rest alone.
