[Bug c/109137] [12/13 regression] Compiling ffmpeg with -m32 on x86_64-pc-linux-gnu hangs on libavcodec/h264_cabac.c since r12-9086-g489c81db7d4f75

--- Comment #2 from Sam James <sam at gentoo dot org> ---
(I suspect ffmpeg's build system does some
buffering/synchronisation/suppression of output until a job is complete which
is why it looks like a hang with no output at all, while running it manually
gets errors-then-hang.)
