> e.g. 'march_base': ['-march=armv8.1-a', '-march=armv8.2-a']
> 2. Define 'march_feature' tuple which defines support feature.
> e.g. 'march_feature': ['crypto', 'sve']
> Note: If user defined 'march_feature', it also needs to define a valid
> 'march_base' because 'march_feature' depends on 'march_base' when
> checking validity.
> 3. Select the most suitable march+feature combination based on
> 'march_base' and 'march_feature' tuples.
> 4. Use the selected march+feature combination as the default
> machine_args.
