Hi Kelvin,

405 does not have VSX (or even VMX).  The instructions enabled by
-mpower9-minmax require VSX.  The following behaviours all make
sense, for -mcpu=405 -mpower9-minmax:

1) Ignore the latter option;
2) Give a warning;
3) Give an error.

The following do not make sense:

1) Enable VSX;
2) Select -mcpu=power9 instead;
3) Omelette du fromage.
