Hi Naveen,

   Now I know your problem is in native building and the reason is
missing proper $(ARCH). I think other than that there's another problem
in libbpf's building: if your problem is unable to compile libbpf,
feature checker should find it and set NO_LIBBPF=1 for perf, so perf
building won't be blocked, only BPF related features should be turned
off. Also, I think including Makefile.arch from tools/scripts would be
better, because libbpf is at the same level with perf. So I separate
them into 3 patches. Please help me test it on PowerPC.
