As Jonathan noticed in [1], users' applications may depend on opencv-2.4
APIs removed in opencv-3.0.
So, re-introduce opencv package as it was right before the bump to
opencv-3.0 (i.e.: commit bf00b5a9ea1ab4189fe5c7dea05f40d0bbbf2082).
We do not support both OpenCV-2.4 and OpenCV-3 at the same time, so make
OpenCV-3 depend on !OpenCV-2.4.

[yann.morin.1998@free.fr:
- remove legacy symbols, now
- make opencv3 depends on !opencv, not the other way around
- slitghly reword the commit log (opencv/opencv3 dependency)

This major version bump is in fact a bump from 2.4.10 to 2.4.11, then to
3.0.
OpenCV-2.4.11 improves a lot the Buildroot integration, including a
couple of patches that are no longer needed:
- x86 PIC code compilation fix in core module [1];
- return type fix in superes module [2];
- opencv.pc generation [3].
It also improves the gstreamer-0.10/1.x detection [4], that will be
needed in a follow-up patch.
OpenCV-3.0 still requires 2 patches (backported from upstream fixing
pthread support [5,6].
The OpenCV-3.0 does some major changes, for which a transition guide
has been published [7].
Among these changes coming with OpenCV-3.0, some new modules have been
introduced and others got removed; leading to a bunch of configure
option updates (to keep as much as possible an iso-functional-perimeter)
and the legacy menu has been updated too.
The worth noticing removals being:
- the opencv_legacy and opencv_nonfree modules no longer exist;
- the opencv_contrib module has moved out of the opencv base tree and
now has its own repository [8].
There is currently no plan to support it.
Some 3rd-party supports have been improved or added; their integrations
in Buildroot will be addressed in follow-up patches.

This change fixes build of packages depending on opencv and using
pkg-config to get the opencv LDFLAGS, which were wrongly ordered for
static build and included absolute path pointing to the host system
libraries instead of the sysroot ones.
This patch fixes build issues with gst1-plugins-bad and vlc.
This change introduce and new patch to opencv, which is already merged
upstream [1].
Fixes:

... and many others
