[Marcelo Tosatti]

Subject says it all, there is no need to link perfmon.o on 
sub-architectures other than CONFIG_E500.

Hrm... Nobody has an implementation for 74xx ?

Ben.

I've got some untested code for 74xx (probably only 7450 for now),  
but it's several rungs down my priority list right now.  :

OK - you can then add the proper change for inclusion inside
the #ifdef ?

Please apply the patch (or some variant of it).
