New issue by RossComputerGuy on void-packages repository

https://github.com/void-linux/void-packages/issues/28711

Description:
I've noticed `xbps-src` has no parallel package building. I think it would be beneficial to support a method to build packages in parallel instead of sequentially. This with parallel compiling and distcc could bring compile times down by a lot on large packages when multiple packages are rebuilt. Maybe a `-pJ` flag (package-jobs) would set how many packages to build at once. Since `xbps-src` is written as a shell script, there's most likely a way to figure this out.
