For me this option looks more elegant. If we will have it as a call in
OSystem or common/utils.h then we will end up with those flags
everywhere.

Another nice feature would be to make possible to disable each
cpu-specific code from command line, i.e. something like
  --disable-altivec, --disable-mmx
or
  -disable altivec,mmx,3dnow,all

So even if certain processor feature is present, it could be
intentionally turned off.
