Add basic PowerPC core tune config (From OE-Core rev: 3212029f0967dd353fec8cc147d2b95031d1018a) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

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.

conf/machine/tune: Overhaul tune include file variables There is currently consideradble confusion over how the tune files operate and how these interact with the rest of the build system. This update/overhaul changes things so the tune files are primarily resonsible for setting: TUNE_ARCH - What was formerly set as TARGET_ARCH and is the value that represents the architecture we're targetting. TUNE_PKGARCH - The value that represents the tune confuration that this set of tune parameters results in. This allows the significant improvement that the core can now always determine the target architecture value, even when TARGET_ARCH needs to be reset to something different and likewise, there is one package architecture variable the core can reference allowing simplification of the BASE_PACKAGE_ARCH, PACKAGE_ARCH and FEED_ARCH variables.

TUNE_CCARGS += "${@bb.utils.contains("TUNE_FEATURES", "ppce500mc", "-mcpu=e500mc", "", d)}"
tune/ppc: Fix various TUNE_PKGARCH issues We need to ensure only one value ends up in TUNE_PKGARCH rather than several. This change ensures consistency accross all the PPC tune files and that they correctly inherit the core value but also allow it to be overwritten.
