I've compared new tune files with tune-cortexa8 (after s/a15/a8; s/a7/a8) and
there are some differences:
< TUNE_FEATURES_tune-cortexa8thf-neon ?= "${TUNE_FEATURES_tune-armv7ahf-neon}
cortexa8"
---
> TUNE_FEATURES_tune-cortexa8thf-neon ?= "${TUNE_FEATURES_tune-armv7athf-neon}
> cortexa8"
36c36
< PACKAGE_EXTRA_ARCHS_tune-cortexa8thf-neon =
"${PACKAGE_EXTRA_ARCHS_tune-armv7athf-neon} cortexa8hf-vfp cortexa8hf-vfp-neon
cortexa8t2-vfp cortexa8t2hf-vfp-neon"

OE @ ~/openembedded-core/meta/conf/machine/include $ diff tune-cortexa7.inc
tune-cortexa8.inc
< TUNE_FEATURES_tune-cortexa8thf-neon ?= "${TUNE_FEATURES_tune-armv7ahf-neon}

I guess it's because a7/a15 were created from a9 which has the same issue (only
a8 was fixed)
I'll send patch to fix those, but please test it.
