ia32 implies 32bit, while these files provide descriptions for IA32,
X86_64, and X32 architectures. The term "x86" fits this used better
without resorting to using the term "Intel" which isn't quite right as
it excludes things like the tune-c3 file describing a Via CPU.

* number of TUNE_CCARGS conditionals is important if we add
extra space with each one in "else" branch
I'm building for 2 MACHINEs one is cortexa9, second is cortexa8
few months ago we added TUNE_CCARGS[vardepvalue] in bitbake.conf
http://git.openembedded.org/openembedded-core/commit/?id=03f1e34ea3ce80931e9c3cd2ab22824f28a7233b
which fixed some cases (like mentioned tune-xscale and tune-arm926ejs)
where both had unused TUNE_CCARGS when common DEFAULTTUNE was used.
with cortexa[89] it's different, because cortexa9 has one extra TUNE_CCARGS
TUNE_CCARGS += "${@bb.utils.contains("TUNE_FEATURES", "cortexa9", "-mtune=cortex-a9", "", d)}"
which adds extra *space* even when not used because of '+=' and as result:

This cleans up and/or corrects a few values from machine includes
for consistency with future toolchain sanity checks, and also adds
the TUNEVALID and TUNECONFLICTS to documentation.conf.

We perform a basic cleanup of the IA32 architecture and related
tunings in order to match the rules and descriptions within the
new tuning README file.
A number of small issues were corrected in the "c3" tuning to
bring it inline with the README.

These changes revolve around the idea of tune features. These are represented by
'flag' strings that are included in the TUNE_FEATURES variable.
Any string included in TUNE_FEATURES should also add a TUNEVALID[<name>] entry so
we can know which flags are available in TUNE_FEATURES and have documentation about
what the flags do. We will add sanity code to error if flags are listed in
TUNE_FEATURES but are not documented in TUNEVALID.
A given tune configuration will want to define one or more predetermined sets of
_FEATURE flag lists. These are defined in the form TUNE_FEATURES_tune-<name>.
For defined tune configuation, <name> should be added to the AVAILTUNE list so that
we can determine what tune configurations are available. Flags cannot be used in this
case as with TUNEVALID since its useful to be able to build up tune lists from other
TUNE_FEATURES_tune-yyy options.
A given tune configuration may also define PACKAGE_EXTRA_ARCHS_tune-<name> and
BASE_LIB_tune-<name> to control the multilib location. All options can be overridden
by the distro or local user configuration.

Since we're updating the tune file format, it makes sense to abstract
the compiler tune arguments at this point too. This means that should
these need to be overridden at any point, the original values can
still be obtained in a similar manner to the other TUNE* variables.
Whilst this isn't strictly necessary for any current need, its likely
good practise to standardise this behaviour.

There is currently consideradble confusion over how the tune files operate
and how these interact with the rest of the build system. This update/overhaul
changes things so the tune files are primarily resonsible for setting:
TUNE_ARCH - What was formerly set as TARGET_ARCH and is the value that
represents the architecture we're targetting.
TUNE_PKGARCH - The value that represents the tune confuration that this set
of tune parameters results in.
This allows the significant improvement that the core can now always determine
the target architecture value, even when TARGET_ARCH needs to be reset to
something different and likewise, there is one package architecture variable
the core can reference allowing simplification of the BASE_PACKAGE_ARCH, PACKAGE_ARCH
and FEED_ARCH variables.

There is a problem with the current PACKAGE_EXTRA_ARCHS implementation
since its impossible to control which extra architectures sort higher
than TARGET_ARCH and which sort lower. In the x86 case for example,
TARGET_ARCH might be "i586", i486 should be lower than this and i686 should
be higher. There are also complications where its easy to inject duplicate
entries into the variable.
I tried various versions of this patch and concluded that it was simplest
just to force the tune files to include TARGET_ARCH in the list in the
right place if they're planning to customise it themselves. Other approaches
with appends and prepends just complicated the code for no good reason.
The TARGET_ARCH definitions should also move to the tune files but I'll
leave this for a separate patch.

This gets us closer to making including tune-<arch>.inc "just work".
Moving the TARGET_ARCH definitions is something for a follup patch.
