I tried to download the .deb file with wget and found out that the remote server disconnects and cancels de download

```

Even in a browser download disconnects! Anyway, my workaround was to download the deb with `wget -c` and put it in `hostdir/sources/spotify-1.1.42/` then the binary builds correctly.

Is there a way to tell xbps-src to retry the download (with resume) for X times?
