perf build is currently (v4.4-rc5) broken on powerpc:
bpf.c:28:4: error: #error __NR_bpf not defined. libbpf does not support your arch. # error __NR_bpf not defined. libbpf does not support your arch. ^
Fix this by including tools/perf/config/Makefile.arch for the proper $ARCH macro. While at it, remove redundant LP64 macro definition.
