Then maybe it's a different issue than what I see here.  Since this is
not a -Q session, I don't know what you load there.  Suggest to start
Emacs under GDB with a breakpoint in Fload, and see what are we
loading that leads to those two.

In general, if you let Emacs native-compile everything it loads at
startup, the next startup it will not need to compile anything, since
the *.eln files are already available.  So if anything still tries to
load and thus native-compile those *-loaddefs files should be the
stuff you load itself, not the compilation infrastructure.

OTOH, I don't see a problem in Emacs starting an async compilation
that ends up not compiling anything.  It runs in the background, so I
don't think it interferes with anything?
