 Summary of the bug:

 If you have libjack installed in the system it is impossible to build
 ffmpeg with linking it to libjack.so

 It seems the same is valid for SDL. It may as well be for other libraries.

 How to reproduce:

 1. Have libjack installed in the system

 2. ./configure --disable-indev=jack

 $ cat work/ffmpeg-2.1/config.log | grep jack
 jack_indev
 jack_indev
 jack_indev=no
 jack_indev_deps='jack_jack_h sem_timedwait'
 list=jack_indev
 name=jack_indev

 $ cat work/ffmpeg-2.1/config.h | grep -i jack
 #define HAVE_JACK_PORT_GET_LATENCY_RANGE 0
 #define CONFIG_JACK_INDEV 0

 $ ldd work/stage/usr/local/bin/ffmpeg|grep -i jack
      libjack.so.0 => /usr/local/lib/libjack.so.0 (0x803a78000)
