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.

Cleanup the ARM tunings to match the new tunings README file.
The ARM tunings define TUNE_PKGARCH in a way that only one main
arm architecture, i.e. armv6, may be defined at the same time. We
may have to revise these settings in the future, as well as figure
out a way to better differentiate various optimize tunings in the
package arch. (This was not done, to preserve existing behavior!)
Fix a number of minor issues w/ the armv5 tunings where DSP variants
were referenced but not defined.
Fix incorrect armv7 entries in armv7a.
Fix PACKAGE_EXTRA_ARCHS definitions inside of tune-cortexm3 and tune-cortexr4.

armv7 is least common denominator of armv7-a
armv7-m and armv7-r and armv7-m does not support
ARM instructions but only thumb2 instruction set
which means armv7 when chosen will complain if
code is compiled in arm mode which is default
in OE if not specified other wise
if we chose this tuning errors like below pop up
error: target CPU does not support ARM mode
This tuning seems theoretical and base tune
for armv7 would be one of armv7-a, armv7-m or
armv7-r

Using "1" with getVar is bad coding style and "True" is preferred.
This patch is a sed over the meta directory of the form:
sed \
-e 's:\(\.getVar([^,()]*, \)1 *):\1True):g' \
-e 's:\(\.getVarFlag([^,()]*, [^,()]*, \)1 *):\1True):g' \
-i `grep -ril getVar *`

Recent versions of the GCC reject the -mno-thumb option. In order to prevent
the compiler from generating code for the Thumb instruction set the -marm
switch should be used instead. For details see GNU bug #47930.

The previous commit to this file meant thumb was always being turned on
even when TUNE_FEATURES did not contain "thumb". This is clearly wrong
and this patch corrects this so thumb options are no longer specified
in that case.

PACKAGE_EXTRA_ARCHS_tune-armv5eb needs to be defined in terms of
the non-e with the same endianness, i.e. PACKAGE_EXTRA_ARCHS_tune-armv5b
not PACKAGE_EXTRA_ARCHS_tune-armv5, otherwise PACKAGE_EXTRA_ARCHS will
end up containing a semi-random mixture of endiannesses and disaster
will ensue. Likewise for the vfp and armv6 variants.
This is all a bit confusing because TUNE_FEATURES is done the opposite
way around, i.e. TUNE_FEATURES_tune-armv5eb is derived by taking the
armv5e version and adding bigendian. But fixing that is probably
a subject for a separate patch.

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.
