Reverse the order of OVERRIDES
Given the current implementation of OVERRIDES in bitbake, the variable is expected to contain elements in the order least specific to most specific, however, our current usage of it does not match that. As one example, "local" is supposed to always be the most specific override, yet currently it's the least specific. As another example, currently the target architecture is seen as more specific than the machine, which is also clearly wrong. Big thanks to Chase Maupin for investigating and identifying this long standing issue. It becomes clear that a reversal of the current value will bring us to a more sane behavior, and avoids the need for the dual overrides hack mentioned in the comments, so this implements this reversal, and drops the unnecessary and confusing comments. This also introduces a MACHINE_OVERRIDES variable as a generic mechanism to inject overrides elements which are more specific than the distro but less specific than the machine, which is where things like MACHINE_CLASS or SOC_FAMILY or the like would go. This variable is *space* separated, to make it easier and more convenient to assemble the variable incrementally.
