[OE-core] [PATCH 0/1] Change default for cortexa* to armv7at-neon.

The various cortex chips generally support thumb code, so the armv7at
tunings are a better default for them than the plain armv7a tunings.
The armv7at tuning allows generation of both arm and thumb code, while
armv7a only allows arm code, which is typically significantly bigger.
(It may be faster in some cases, but the tradeoffs aren't totally
obvious, because smaller code fits in caches better.) Since they
all had armv7a-neon as default, change them to armv7at-neon.

The following changes since commit 47d1fc9f5c38f3d092937c47bd4c2f45adaa7fe6:
