There's a merged pull request on the void-packages repository

Add vtargetrun (run executables with qemu) and vcompletion (install helper for shell completions);  use them in rustup and starship
https://github.com/void-linux/void-packages/pull/22785

Description:
Inspired by #22761 . Pinging @sgn 

Not revbumping because I don't think it's urgent. I could see the case for making this procedure part of the cargo build style, configurable with some variable like `clap_completions=yes`.

If you feel it adds too much complexity for little gain, I can close the PR.
