[OE-core] [PATCHv2] ARMv8 32-bit compiler tunings

[Daniel Dragomir]

Hello!

This is a second version for the patch:
http://lists.openembedded.org/pipermail/openembedded-core/2016-February/117603.html

I remove the python method from feature-arm-vfp and I added the TUNE_CCARGS appends for CRC, CRYPTO and fp-armv8 only in armv8a tune file.
I fix some parsing failures for armv7a*-neon-vfpv4 tunes.
Also, I reworked the tunes to eliminate multiple parsing failures that I got running Martin's script.

@Martin, I ran again the script and the results are better. I pushed the results in a personal repo:
Tune results without the patch - clean open-embedded:
https://github.com/ddragomi/tune_test/tree/14861fd72be9aebaaa209d9990d72745c90b43eb/tune

Tune results with this patch (VERSION 2):
https://github.com/ddragomi/tune_test/tree/master/tune

And a diff between those here (I fix some parsing failures for armv7a*-neon-vfpv4 tunes):
https://github.com/ddragomi/tune_test/commit/06fbd558bf7e5d91d312628a023b8c0495e8f37a

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.

Best regards,
