[PATCH] ppc32: fix build with oprofile
Current -git tree doesn't build when enabling oprofile on a non-bookE CPU (like on a PowerMac for example). While there is no performance counter support for these CPUs implemented yet, it's still nice to be able to use the timer based sampling, and that got broken.
