[PATCH 08/12] tools: Move Makefile.arch from perf/config to tools/scripts

Arnaldo Carvalho de Melo

After this patch other directories can use this architecture detector
without directly including it from perf's directory. Libbpf would
utilize it to get proper $(ARCH) so it can receive correct uapi include
directory.
