The ELisp manual says about this:

   -- Variable: native-comp-enable-subr-trampolines
       This variable controls generation of trampolines.  A trampoline is
       a small piece of native code required to allow calling Lisp
       primitives, which were advised or redefined, from Lisp code that
       was natively-compiled with ‘native-comp-speed’ set to 2 or greater.
       Emacs stores the generated trampolines on separate ‘*.eln’ files.
