VIA processors such as the C3 are PPro compatible *but* the GNU C
compiler definition of i686 is (was ?) broken and incorrectly used cmov
without checking if it was available. If gcc has been fixed or those
options avoid cmov then it ought to cover any vaguely recent processor
fine (and -mtune=atom seems to produce better code for older processors
than i586)
