Comment:
They need to fix their build:

```
 aarch64-linux-gnu-gcc: error: unrecognized command-line option '-msse'
aarch64-linux-gnu-gcc: error: unrecognized command-line option '-msse2'
aarch64-linux-gnu-gcc: error: unrecognized command-line option '-mfpmath=sse'
```

Specifically, https://github.com/lucianodato/noise-repellent/blob/master/meson.build#L23 is just wrong.

It's not build machine that matters, it's the `host_machine`, and checking if `arch` isn't `aarch64` to enable x86_64 only optimization is also wrong, since they should be checking if arch is `x86_64`. I might make a PR their way later to fix this.
