* configure.ac, irq/irq.c, startup/bspclean.c, startup/bspstart.c: Add ALLOW_IRQ_NESTING option. The MPC5200 has a settle time after acknowledging the IRQs and currently the BSP does not account for that. After acknowledging an interrupt, it currently gets a second spurious IRQ a significant percentage of the time. Rename to BENCHMARK_IRQ_PROCESSING and get it working again. Under one test load, not nesting interrupts resulted in a 50% reduction in the number of IRQs and an ~30% reduction in time spent in IRQs.
