 ffmpeg doesn't respond to SIGINT on debian sid when using a `-f pulse`
 input device.

 Trying to send SIGINT through `Ctrl+C` or through `kill -2 {pid}` has no
 response. Stopping with `q` still works.

 Running under valgrind ffmpeg does respond to sigint.

 Removing any of the configure flags will cause the bug to dissapear
 (Except libpulse and prefix which are required to test it in the first
 place)

 {{{
 ./configure --enable-libopencv --enable-libpulse --prefix=/home/j/FFmpeg
 --enable-gnutls --shlibdir=/usr/lib/x86_64-linux-gnu
 }}}

 Note about the output below. There are warning lines like so:
 {{{
 avutil      configuration: [...]
 }}}

 But these lines disappear when configured with `--libdir=/usr/lib/x86_64
 -linux-gnu` though the bug persists so I've cut them out of the output to
 make it more readable.

 How to reproduce:
 {{{
 git clone git at github.com:FFmpeg/FFmpeg.git
 cd FFmpeg
 ./configure --enable-libopencv --enable-libpulse --prefix=/home/j/FFmpeg
 --enable-gnutls --shlibdir=/usr/lib/x86_64-linux-gnu
 make
 make install
 cd ~
 ./FFmpeg/bin/ffmpeg -f pulse -i default -c copy out.avi
