e467705a9f 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.

a701d28e2d perf annotate mips: Add perf arch instructions annotate handlers 
Support the MIPS architecture using the ins_ops association method. With
this patch, perf-annotate can work well on MIPS.

Testing it with a perf.data file collected on a mips machine:

$./perf annotate -i perf.data

93df8a1ed6 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.
