Because it's always compromise between optimizing for given device and sharing the same DEFAULTTUNE (and its binary feed) for many MACHINEs suppor= ted by DISTRO. Even enabling thumb seems wrong, because ARM_INSTRUCTION_SET is arm by default, so this change is only renaming the feed, but still building the same binaries (unless distro sets ARM_INSTRUCTION_SET).
