Comment (by ahthovaikied):

 I don't know why, but when doing a bisect a very large proportion of
 versions fails to build with {{{--disable-vaapi --disable-vdpau}}} (I's
 say 90%), with link errors like for example:
 {{{
 libavcodec/libavcodec.a(vc1dsp.o): dans la fonction « ff_vc1dsp_init »:
 vc1dsp.c:(.text.unlikely+0x38d): référence indéfinie vers «
 ff_vc1dsp_init_x86 »
 collect2: error: ld returned 1 exit status
 make: *** [ffmpeg_g] Erreur 1
 make: *** Attente des tâches non terminées....

 collect2: error: ld returned 1 exit status
 make: *** [ffplay_g] Erreur 1

 }}}

 I tried playing with configure options, but there is always a large number
 of build which fail and thus the bisect takes forever.
