Subject: [PATCH] contrib: Explicitly pass arch to FFmpeg on macOS x86_64.

Fixes FFmpeg configure error on macOS:

```
./configure: line 588: eval: --: invalid option
eval: usage: eval [arg ...]
make[1]: *** [contrib/ffmpeg/.stamp.ffmpeg.configure] Error 2
```

...caused by attempting to `eval --arch=x86_64=yes`.
