This test will always fail on my system even if libswcale.a is 
installed. It failed the link part of the test.

If ffmpeg always installs libswscale.pc and swscale.h then IMHO ffmpeg 
should be fixed to not do that when --enable-swscaler is used.

The old img_* interface in newer ffmpeg is marked depreceated and is 
replaced by sws_* based interface. For vlc is it thus natural to move on 
to the new interface and drop the old one.
