libgstreamer-plugins-bad1.0-0=1.2.4-1~ubuntu1.1 : undefined symbol: eglDestroyImageKHR

[RJVB]

Just saw this error on an up-to-date KUbuntu 14.04.5LTS system (with the "lts-xenial" stack):

(gst-plugin-scanner:26486): GStreamer-WARNING **: Failed to load plugin '/usr/lib/x86_64-linux-gnu/gstreamer-1.0/libgsteglglessink.so': /usr/lib/x86_64-linux-gnu/libgstegl-1.0.so.0: undefined symbol: eglDestroyImageKHR

I didn't see any reports of the error affecting gst-scanner when I googled the undefined error (https://www.google.fr/search?q=libgstegl-1.0.so.0%3A+undefined+symbol%3A+eglDestroyImageKHR). The results do show that the issue has been around from before I upgraded to the LTS enablement stack, so it may have nothing to do with that at all.

Possibly the package simply needs to be regenerated.

This patch allows building the package (v1.2.4) against libegl1-mesa-lts-xenial 11.2.0 (after also disabling opencv support because one of the required dependencies wouldn't install).
