[OE-core] [RFC][PATCH] bitbake.conf: make OVERRIDES match what people expect

[Koen Kooi]

In the current situation TARGET_ARCH will override MACHINE, which is counter intuitive since the machine is more specific than the arch.

The order is now pn-$PN} -> arch -> machine -> distro as the machine is a set of defaults and the distro is the ultimate policy.

'failfast' has been removed since it's not used anymore, just like 'local'
