[FFmpeg-devel] [PATCH]Remove --disable-avutil and sanitize --disable-all

[Carl Eugen Hoyos]

Hi!

The configure option --disable-avutil has no effect, --disable-all does not 
disable avutil (it never has), but it currently disables all dependencies 
of libavutil in an unexpected way: A library that was never disabled has to 
be enabled (with --enable-avutil) to enable dependent options.
Attached patch fixes this behaviour, to be split.
