linux: NEON instructions are not enabled for Omnia
When running 3rd party LXC container compiled for armhf,
wget exited with SIGILL. According to
gdb, the offending instruction was
vld1.64, which is a NEON instruction. I do not have kernel config at hand (btw. having
/proc/config.gz would be nice), but it seems that
CONFIG_NEON=y is not present in kernel 4.4 (it was in 4.1).
If there's no reason for not having NEON instructions enabled, we should re-enable them.
