Bug description:

While working on reproducible builds for openSUSE, I found that
our Python-3.14.0rc2 package has random variations in one of its files:

--- old//usr/src/debug/Python-3.14.0rc2/jit_stencils-x86_64-suse-linux-gnu.h
+++ new//usr/src/debug/Python-3.14.0rc2/jit_stencils-x86_64-suse-linux-gnu.h

 // $ python3.13 ./Tools/jit/build.py x86_64-suse-linux-gnu --output-dir . --pyconfig-dir . --cflags=

 void

It would be better to have all build outputs deterministic.
