Errors like:
```
/usr/lib/gcc/arm-linux-musleabihf/9.2.0/../../../../arm-linux-musleabihf/bin/ld: /usr/arm-linux-musleabihf/usr/include/c++/9.2.0/atomic:254: undefined reference to `__atomic_load_8'
```

Usually mean that you need libatomic for the architecture. This can be done by conditionally adding `libatomic-devel` to makedepends and linking with `-latomic`. You can find an example of this in the libfilezilla template.
