[FFmpeg-user] d4cd8830bd breaks build on AMD Ryzen

Wed Apr 27 20:26:23 EEST 2022

I have an AMD Ryzen Threadripper PRO 3975WX (32-Cores). I tried to
build HEAD (4fc806bbe612784286f123af92a0d5d0da333064), but it fails:

```

I bisected the build, and can see:

```

but:

```
$ git reset --hard d4cd8830bda~
$ make -j
...
STRIP ffprobe
STRIP ffplay
STRIP ffmpeg
```

In case it helps, this is my CPU:
