New review comment by agausmann on void-packages repository

Comment:
These dependencies are also set for the flavor packages, causing for example `rpi4-kernel` to depend on `rpi3-kernel`, since `rpi4-kernel` is built for `aarch64`. This is definitely unwanted, and causes problems with `./mkplatformfs.sh rpi4 ...` when it attempts to install both `rpi3-kernel` and `rpi4-kernel`, as the files will conflict.
