As it's now adding it to TUNE_FEATURES it would duplicate -mfpu options
with different values, this change should probably cover vfpv3 and
vfpv3d16 as well as added in:

commit f9de9521477a1de8f6a399bcdc8260e28e34dfb3
Author: André Draszik <git at andred.net>
Date:   Fri Jul 24 14:14:30 2015 +0100

    arch-armv7a.inc, feature-arm-vfp.inc: add tunes for vfpv3 and
vfpv3d16

vfpv4 as separate TUNE_FEATURE was added in:

commit e97d152ca13556b41a236c1a4cfb11e77ff857d7
Author: Kristof Robot <krirobo at gmail.com>
Date:   Sun Jan 26 10:03:56 2014 +0100

    Add Cortex A7 support for NEONv2 & FPv4

So you should probably ask Kristof or Andre why they didn't include vfp
as well. I'm just trying to fix missing -mfloat-abi=hard when switching from
vfp to vfpv4.
