Description
While working on reproducible builds for openSUSE, I found that
various rust packages produced different binaries in every build,
even when trying to run builds as similar as possible.
versions:
- openSUSE Tumbleweed 20231108
- libLLVM17-17.0.4
- rust-1.73
affected packages:
- contrast
- difftastic
- rage-encryption
- sad
- tiny
Diffs (from filterdiff strings {1,2}/usr/bin/sad) look like this:

rust_panicso it seems there is some random number appended and that influences ordering.
