tools/perf/build: Add 'autodep' functionality, generate feature test dependencies automatically
...
Use GCC's -MD feature to generate a dependency file for each feature test .c file,
and include that .d file in the config/feature-checks/Makefile.
This allows us to do two things:
- speed up feature tests
- detect removal or changes in build dependencies - including system libraries/headers

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.
