Make CPU_MODELS a sticky build option.

Browse source 
This causes a crash if you're using scons 0.96.1 *and* you specify
more than one CPU model.  Since the .isa scanner now works with 0.96.91
then upgrading should not be an issue.  For now we're only using one CPU
model (SimpleCPU) so there isn't even a pressing need to upgrade yet.
