[OE-core] [master][PATCH] ARMv8 32-bit compiler tunings

[Daniel Dragomir]

Hello!

This is a new version for the patch, against master branch:
http://lists.openembedded.org/pipermail/openembedded-core/2016-February/117603.html

@Martin, I pushed the results from testing with your script in a personal repo:
Tune results without the patch - clean open-embedded (master branch):
	https://github.com/ddragomi/tune_test/tree/3f4054dd96e9d96c18e1eb9c5fef9f5ebc77f4a3/tune

Tune results with this patch:
	https://github.com/ddragomi/tune_test/tree/ff9c904fa6fff38efdc72c604e6d5677b64f76a5/tune

And a diff between those here:
        https://github.com/ddragomi/tune_test/commit/ff9c904fa6fff38efdc72c604e6d5677b64f76a5

NOTE: I also added a new fake-machine (axxiaarm) that require arch-arm8a.inc
to test/parse armv8a tunes:
DEFAULTTUNE ?= "armv8a-neon"
require conf/machine/include/arm/arch-armv8a.inc

Previous message:
Starting with linux-yocto-4.1, Intel provides kernel support for its
ARM v8 Axxia platforms, both on 32-bit and 64-bit.
Poky already contains arm 64-bit compiler tunings, so I added 32-bit
tunings based on those for armv7.

The patch that I send you is a draft. Please review it and if it's ok
I will return with thumb and big-endian tunings.
