 This will get more readable if you use `./configure --toolchain=clang-asan
 && make ffmpeg_g`, feel free to add `--disable-asm`.

 This is unfortunately useless, use `ffmpeg_g` instead and post everything
 that gets printed, not only the part you consider important (we disagree).

 Please do not use zip here and please explain what "JIT" means.
