Build with docker failed

Hi, I'm building ffmpeg.wasm-core on Ubuntu server with `./build-with-docker.sh`, the error message:

```

I saw the same error in ffmpeg.wasm-core Github Action: https://github.com/ffmpegwasm/ffmpeg.wasm-core/runs/2598825955?check_suite_focus=true seams it's broken since v0.9.0
