To be honest, I don't understand what you mean by the first sentence.
The linked message didn't say it's w/o native-compilation?

Let me add another question, just to be as precise as possible:
I understand We have differences between 2 independent builds with
native compilation. When you say executable and pdmp differ without
native compilation, do you mean between 2 builds both without native
comp?
> Build log without native-comp:
Not of great help, I'm afraid. Lots of stuff nobody wants to know, here
at least :-).
Anyway--what are these CFLAGS for, esp. -DPDMP_BASE=...? I don't know
what they do.

I'd recommend simplifying things by building Emacs with standard options
(no CFLAGS=...) and without any of your build tools. Just 2 clean build
directories, and then compare.
