Comment:
I also cross-built it succesfully on x86_64-musl with:
```./xbps-src -a aarch64 -j16 pkg icewm```
```./xbps-src -a armv7hf-musl -j16 pkg icewm```

But I couldn't find a way to check the validity of the checksum, I just copy-pasted the one from the xbps-src error message. The checksum on the release page is not for the .tar.gz source package, and the .tar.lz is not the same content.

This PR should supersede the previous for 3.2.3: #40997
