conf/machine/include: Start to fill out architecture specific tune include files and tune features These changes revolve around the idea of tune features. These are represented by 'flag' strings that are included in the TUNE_FEATURES variable. Any string included in TUNE_FEATURES should also add a TUNEVALID[<name>] entry so we can know which flags are available in TUNE_FEATURES and have documentation about what the flags do. We will add sanity code to error if flags are listed in TUNE_FEATURES but are not documented in TUNEVALID. A given tune configuration will want to define one or more predetermined sets of _FEATURE flag lists. These are defined in the form TUNE_FEATURES_tune-<name>. For defined tune configuation, <name> should be added to the AVAILTUNE list so that we can determine what tune configurations are available. Flags cannot be used in this case as with TUNEVALID since its useful to be able to build up tune lists from other TUNE_FEATURES_tune-yyy options. A given tune configuration may also define PACKAGE_EXTRA_ARCHS_tune-<name> and BASE_LIB_tune-<name> to control the multilib location. All options can be overridden by the distro or local user configuration.
