Subject: [PATCH 2/4] perf version: update --build-options to use 'supported_features' array

Now that the feature list has been duplicated in a global
'supported_features' array, use that array instead of manually checking
status of built-in features.

This helps in being consistent with commands such as 'perf check --feature',
so commands can use the same array, and any new feature can be added at
one place, in the 'supported_features' array
