[oe] [meta-oe][PATCH] ne10: set NE10_TARGET_ARCH with an override instead of anonymous python

[Martin Jansa]

* set COMPATIBLE_MACHINE to (^$) to prevent building it for any other
  architectures than armv7a and aarch64
* with new arm tune files it's easy to have armv7a in OVERRIDES even
  when there isn't armv7a in TUNE_FEATURES:
  meta/conf/machine/include/tune-cortexa9.inc:7
     "${@bb.utils.contains('TUNE_FEATURES', 'cortexa9', 'armv7a:', '',d)}"
  in cases like this COMPATIBLE_MACHINE was satisfied thanks to the
  armv7a OVERRIDE, but then the anonymous python was failing with:
  ne10 was skipped: Incompatible with archs other than armv7 and aarch64
