Subject: [PATCH] tracing: don't select FRAME_POINTER on PPC

On PowerPC, FUNCTION_TRACER selects FRAME_POINTER, even
though the architecture does not support it.

This causes the following warning:
warning: (LOCKDEP && FAULT_INJECTION_STACKTRACE_FILTER && LATENCYTOP && FUNCTION_TRACER && KMEMCHECK) selects FRAME_POINTER which has unmet direct dependencies (DEBUG_KERNEL && (CRIS || M68K || FRV || UML || AVR32 || SUPERH || BLACKFIN || MN10300) || ARCH_WANT_FRAME_POINTERS)

So remove the warning by adding the extra condition
"if !PPC" to FUNCTION_TRACER for FRAME_POINTER selection
