 Replying to [comment:7 gk]:
 > Okay, time to give an update here. `bug_32053_v2`
 (https://gitweb.torproject.org/user/gk/tor-browser-
 build.git/log/?h=bug_32053_v2) contains two commits that reduce the build
 time while still being able to reproduce the bug. First of all, I am not
 100% yet that LTO is not introducing a second reproducibility issue here
 but disabling it does not solve the bug I am hunting. It has the nice
 side-effect, though, that without LTO the build time of `libgkrust.a` goes
 down another approx. 2 minutes on my faster machine.

 FWIW, I tried to do the same for the linux32 build for #32052, and was
 able to reproduce the issue with `servo.patch` (I did not try with
 `no_lto.patch` yet) while cleaning only `libstyle-*` and `*.a` files after
 each build, and was able to reproduce the issue too.
