[PATCH 0/6] Correct and improve the ARM tunings

[Peter Kjellerstedt <peter.kjellerstedt@axis.com>]

These patches are intended to improve the ARM tunings and came about
after I had to study the tune files a lot more than I first had
anticipated...

The first patch (arch-armv8a.inc: Correct
PACKAGE_EXTRA_ARCHS_tune-armv8a-*) avoids odd architectures such as
"crc" and "crypto" to be included in PACKAGE_EXTRA_ARCHS.

The following three patches (where i have sent the latter two to the
list before) restores the "armv*" features to TUNE_FEATURES for all ARM
based SoCs as it does not make sense to remove them from the SoC
specific tune files just to determine whether -mcpu or -march shall be
used. This is because the SoCs still support the armv* features
specified in their TUNE_FEATURES even if they also have more specific
SoC tunings.

The next patch (arch-arm64.inc: Lower the priority of aarch64 in
MACHINEOVERRIDES) makes sure that ${SOC_FAMILY} (if present) and
${MACHINE} have higher override priorities than aarch64, as should be.

Finally, the last patch (arm-tunes: Add armv8a to TUNE_FEATURES as
appropriate) adds the "armv8a" feature to TUNE_FEATURES for the
Cortex-A32, Cortex-A35, Cortex-A53 and Cortex-A72 to match all the other
ARM tunings.
