Subject: [PATCH v3 11/12] perf jevents: Build support for generating metrics
from python
Generate extra-metrics.json and extra-metricgroups.json from python
architecture specific scripts. The metrics themselves will be added in
later patches.
If a build takes place in tools/perf/ then extra-metrics.json and
extra-metricgroups.json are generated in that directory and so added
to .gitignore. If there is an OUTPUT directory then the
tools/perf/pmu-events/arch files are copied to it so the generated
extra-metrics.json and extra-metricgroups.json can be added/generated
there.
