Bug#721894: libav: FTBFS with opencv 2.4

Hi Nobuhiro,

the configure script tries to link a small test application using the
opencv opencv/cv.h and sees if it can resolve the symbol
cvCreateImageHeader. The necessary libraries are resolved using the
pkg-config .pc file that is provided by the pkg-config file.

Are you sure that the opencv 2.4 .pc file is working correctly? Can
you please provide me with the output of

pkg-config --cflags --libs libopencv

when opencv 2.4 is installed? I would like to compare it to a system
with opencv 2.3 installed. The logfile does indicate some linking
errors, and we need to figure out what is going wrong here.
