tune_features_check.bbclass: Add class
tune_features_check.bbclass: Add class

This class can be used by recipes pulling binaries into the rootfs which
have been compiled outside of the build.
Two variables are provided:

REQUIRED_TUNE_FEATURES and CONFLICT_TUNE_FEATURES

Those can be used to check for basic ABI mismatches. For ABI
compatibility a lot more requirements must be met. QA sanity tests can
provide some information.

The code is based on distro_features_check.bbclass.
