0.29.0: sq is not reproducible

When building the package for Arch Linux I noticed hat sq is not reproducible.

This is the diffoscope output of our rebuilderd instance: diffoscope.log

e.g. diffoscope <file_a> <file_b>

FTR: diffoscope can be used online even: https://try.diffoscope.org/

These issues most often occur due to sections in a build.rs (e.g. unsorted lists, etc.) that introduce this type of behavior for the resulting binary and less often the code itself.
