Busybox config

Hello,

tar xzvf of the linked file fails with "bad tar magic" on Busybox 1.25.0 (config attached), but succeeds on Ubuntu.

https://github.com/Fornoth/spotify-connect-web/releases/download/0.0.3-alpha/spotify-connect-web_0.0.3-alpha_chroot.tar.gz

Other files fail to decompress with "short read".

A quick search found similar symptoms on Alpine and OpenWRT, but no fix, only a workaround: install tar. This is not an option on LibreELEC: Busybox tar should work as expected, and tar is too large. 

Thank you for your assistance,
@
