[Buildroot] [git commit] ffmpeg: fix neon support for aarch64

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=9de0100cf1ef55789d582fce265dd6c536beb6e6
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

ffmpeg ported arm 32-bit NEON code to aarch64 as hard dependency:
http://ffmpeg.org/pipermail/ffmpeg-devel/2016-November/202733.html

Buildroot option BR2_ARM_CPU_HAS_NEON handles only the 32bit case:
https://git.buildroot.net/buildroot/commit/?id=0976cd6cd64a128a2ac921e4f35f0e7cbe306692

For aarch64 we need to make sure to pass --enable-neon in order to
prevent a link error, fixes
