[Buildroot] [git commit] package/opencv3: fix build for x86_64 target

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=86666f3a21a2380e19b5f0de90b6b6329ce3de53
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

This change backports a fix from upstream fixing missing symbols due to
wrong compiler optimization flags.

On Buildroot side, also remove deprecated options passed on the
configure command.
