As far as I can tell, tuning for Sempron doesn't make much sense
since this is not one specific design, but at least two different
ones (the Socket A variant and the Socket 754 variant).

I don't think we should have variants for all sorts of spellings such
as athlonxp vs athlon-xp vs athlon_xp.
And if you check our fine manual, you will see that we actually support
such options.
