First of all, the examples/standalone/Makefile is still using architecture "ppc" instead of "powerpc". The "sched" application is never compiled.

I replace "ppc" with "powerpc" inside this Makefile, the "sched" application is now compiled.

But the "sched" application is not working correctly. Once one thread is finished and returned, there will be a program check exception.
