non-deterministic files in target/ dir

[bmwiedemann]

Problem

For debugging issues with (un-)reproducible builds, one common approach is to diff intermediate files of the build to get closer to the source of non-determinism.

However, there are currently some random variations in generated files in the target/ dir that make it harder to find the relevant diffs.

Steps

1. cargo build && mv target{,.1} && cargo build && diff -u target{,.1}

Possible Solution(s)

PR #16691 addresses one part of these issues.
There is a 2nd change needed.
