Like this? I'm trying to find a way to do ppc cross builds, one more
thing to have in the build-tests...

    perf tools: Fix build break on powerpc
    
    Commit 531d2410635c ("perf tools: Do not include stringify.h from the
    kernel sources") seems to have accidentially removed the inclusion of
    "util/header.h" from "arch/powerpc/util/header.c".
    
    "util/header.h" provides the prototype for get_cpuid() and is needed to
    build perf on Powerpc:
    
            arch/powerpc/util/header.c:17:1: error: no previous prototype for ‘get_cpuid’ [-Werror=missing-prototypes]
