    ftrace: Build without frame pointers on Microblaze

    function tracer.
    
    The patch remove Kconfig warning.
    
    Warning log:
    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)
