perf tools: Add empty Build files for architectures lacking them

perf currently fails to build on MIPS as there is no tools/perf/arch/mips/Build file. Adding an empty file fixes this as there are no MIPS-specific sources to build. It looks like the same is needed for Alpha and PA-RISC, though I haven't been able to test those.
