Understanding that both are valid options (in the sense both can be used) isn't
hard, but understanding that -mtune=k8 and k8-sse3 had the same effect and
that, even in that case, both options are accepted and allowed even being
redundant, didn't look so easy to understand for me.

But, anyway, all is more clear now to me. Thanks a lot for your help and sorry
for the inconvenience
