This or one of the following commits broke linking here:

/home/stefano/src/ffmpeg.git/libavcodec/libavcodec.a(dwt.o): In function `ff_dwt_init':
/home/stefano/src/ffmpeg.git/libavcodec/dwt.c:842: undefined reference to `ff_dwt_init_x86'
collect2: ld returned 1 exit status

I suppose this may be related to the fact that I'm not compiling with
optimization, and ff_dwt_init_x86() is defined in
libavcodec/x86/snowdsp_mmx and maybe it's not compiled (just guessing
to true inspection and no time for that...).

My configure:
/configure \
--prefix=$HOME \
--enable-gpl \
--disable-shared \
--enable-debug=3 \
--enable-pthreads \
--enable-libvorbis \
--enable-avfilter \
--enable-nonfree \
--enable-x11grab \
--enable-libmp3lame \
--enable-libspeex \
--disable-optimizations \

--disable-stripping \
