[OE-core] [PATCH 1/3] Add ARM tune file overhaul based largely on work from Mark Hatle

Hi Mark,Richard
currently qemuarm does not build due to this patch forcing thumb mode
as default for all 't' architectures which could have worked if recipes
using ARM_INSTRUCTION_SET="arm" in them were somehow excluded from
building in thumb mode. Further comments are inline.

this here means we want to generate thumb code by default if one uses
ARMv4t core. Which is ok but find out all the recipes thats using
ARM_INSTRUCTION_SET = arm at present and we have to have a way to
exclude them. I think having them specified here with some override
is not good since it will mean that if some layer has a recipe which can
not be compiled in thumb mode has to have an entry here.
Is it possible to filter out a given TUNE_FEATURE inside a recipe ?

so it seems any achitecture that supports thumb we resport to thumb
intruction set. I dont think thats what we want. We should be able to
select the intruction set on architectures where choice is available
e.g. on armv5t we can use arm or thumb but on armv5 there is no choice
so we have to use arm. and cortex-m3 we have to use thumb2 there is no
other choice etc.

it seems thumb being present in TUNE_FEATURES is meant for generating
thumb code. Which is fine however all packages currently can not be
compiled in thumb mode for various reasons. Most important of all is
eglibc/glibc. It can be compiled in thumb2 but not thumb1 so While we
would like to generate as much thumb as possible its not possible to
compile everything in thumb. So we had ARM_INSTRUCTION_SET which was
used to configure intruction set at recipe level. How do we do that with
this new tune infra ?

here I guess we have to say AVAILTUNES += "arm920t arm920"
where arm920 is arm mode and 920t is thumb mode. but anyway I would
prefer that thumb is optionally added provided user asked for it
through DISTRO/MACHINE features then we should first make sure
that selected machine has thumb feature and if yes for both then we
should enable -mthumb compiler option which now it enable when thumb
appears in TUNE_FEATURES
