Refactor the perf python module build to instead of building C files
it links libraries. To support this make static libraries for tests,
ui, util and pmu-events. Doing this allows fewer functions to be
stubbed out, importantly parse_events is no longer stubbed out which
will improve the ability to work with heterogeneous cores.

By not building .c files for the python module and for the build of
perf, this should also help build times.

Patch 1 adds '*.a' cleanup to the clean target.

Patches 2 to 6 add static libraries for existing parts of the perf
build.

Patch 7 adds the python build using libraries rather than C source
files.

Patch 8 cleans up the python dependencies and removes the no longer
needed python-ext-sources.

v2: Add '*.a' cleanup to clean target. Add reviewed-by James Clark.

Ian Rogers (8):
  perf build: Add '*.a' to clean targets
  perf ui: Make ui its own library
  perf pmu-events: Make pmu-events a library
  perf test: Make tests its own library
  perf bench: Make bench its own library
  perf util: Make util its own library
  perf python: Switch module to linking libraries from building source
  perf python: Clean up build dependencies
