[Buildroot] [git commit branch/next] package/opencv: add openmp support

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=7a76c358fae668db53de13e9ace6f90e03ef3d3a
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/next

Note that this situation is not ideal because it only add openmp support
to the Buildroot toolchain, not the external ones; but a couple of
packages already are in this situation.
