perf util: Make util its own library

Make the util directory into its own library. This is done to avoid
compiling code twice, once for the perf tool and once for the perf
python module. For convenience:
arch/common.c
scripts/perl/Perf-Trace-Util/Context.c
scripts/python/Perf-Trace-Util/Context.c
are made part of this library.

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.
