* add TUNE_CCARGS_MFLOAT variable which is used to set -mfloat-abi
parameter as well as ARMPKGSFX_EABI suffix in TUNE_PKGARCH and
TARGET_FPU
* TARGET_FPU was using ARMPKGSFX_FPU, but in most cases we use it
only to distinguish between hard and soft abi, not various -mfpu
variants which can appear in ARMPKGSFX_FPU

* respect all 4 vfp options ('vfp', 'vfpv3d16', 'vfpv3', 'vfpv4') when
setting -mfloat-abi and ARMPKGSFX_EABI, without this change it wasn't
possible to use call-convention hard together with vfpv4
* move 'vfpv3d16', 'vfpv3', 'vfpv4' support from
feature-arm-vfp.inc
to
feature-arm-neon.inc
the main difference is that feature-arm-vfp.inc is included in
arch-armv5.inc while feature-arm-neon.inc only in armv7*.inc, so
these options should be added to TUNEVALID also only for armv7*
MACHINEs.
* support vfpv4 with or without neon
when both vfpv4 and neon are in TUNE_FEATURES we want to set only one
-mfpu parameter and to neon-vfpv4
* prevent multiple appends to ARMPKGSFX_FPU, we don't want to include
e.g. -vfp as well as -vfpv4 when both "vfp" and "vfpv4" are in
TUNE_FEATURES
* add -mfpu=vfp for tunes with "vfp" in TUNE_FEATURES - before that we
were only adding -vfp to ARMPKGSFX_FPU
* add TUNE_CCARGS_MFPU variable which is used to set -mfpu parameter as
well as ARMPKGSFX_FPU suffix in TUNE_PKGARCH, all enabled values are
appended to it based on TUNE_FEATURES and then the last one is used
in the actual param and suffix
* this prevents multiple -mfpu options in TUNE_CCARGS
* !!!
This means we need to change TUNE_PKGARCH and PACKAGE_EXTRA_ARCHS for
vfpv4, vfpv3d16, vfpv3 tunes, because the -vfp* isn't prependend
multiple times. If you're using one of these new DEFAULTTUNES (which
were at least partially broken anyway) and depend on working binary
package feed upgrade-path, then don't forget to migrate PR service
database to new TUNE_PKGARCH.

This adds tunes for ARM's v3 Vector Floating Point unit for
16 and 32 bit implementation:
http://www.arm.com/products/processors/technologies/vector-floating-point.php
See also https://wiki.debian.org/ArmHardFloatPort/VfpComparison
for a nice comparison and why vfpv3d16 is useful.

* 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:
