package/opencv3: allow to use pkg-config while cross-compiling
Since version 3.4.1 [1], opencv disable pkg-config while cross-compiling to avoid host headers/libraries poisoning. Due to this, opencv fail to detect ffmpeg, gstreamer and gtk dependencies even if the corresponding support is requested by BR2_PACKAGE_OPENCV3_WITH_{FFMPEG,GSTREAMER,GTK2,GTK3}. Maybe other dependencies are affected by this issue... While configuring opencv we can notice the following messages: "-- OpenCV disables pkg-config to avoid using of host libraries. Consider using PKG_CONFIG_LIBDIR to specify target SYSROOT" "-- Can't find ffmpeg - 'pkg-config' utility is missing" As the result ffmpeg and gstreamer are not enabled: -- Video I/O: -- FFMPEG: NO -- avcodec: NO -- avformat: NO -- avutil: NO -- swscale: NO -- avresample: NO -- GStreamer: NO -- libv4l/libv4l2: NO -- v4l/v4l2: linux/videodev2.h We can fixes this by adding a new option OPENCV_ENABLE_PKG_CONFIG=ON -- Video I/O: -- FFMPEG: YES -- avcodec: YES (ver 58.35.100) -- avformat: YES (ver 58.20.100) -- avutil: YES (ver 56.22.100) -- swscale: YES (ver 5.3.100) -- avresample: YES (ver 4.0.0) -- GStreamer: -- base: YES (ver 1.16.0) -- video: YES (ver 1.16.0) -- app: YES (ver 1.16.0) -- riff: YES (ver 1.16.0) -- pbutils: YES (ver 1.16.0) -- libv4l/libv4l2: NO -- v4l/v4l2: linux/videodev2.h Add host-pkgconf in the dependencies. If there is a path poisoning issue, it will be detected by the toolchain paranoid wrapper.
