tools/perf/build: Add feature check core code Start the split-out of the feature check code by adding a list of features to be tested, and rules to process that list by building its matching feature-check file in config/feature-checks/test-<feature>.c. Add 'hello' as the initial feature. This structure will allow us to build split-out feature checks in parallel and thus speed up feature detection dramatically. No change in functionality: no feature check is used by the build rules yet.
