Good question.  That commit was indeed supposed to deal with this, but
I didn't yet have time to actually test it with a sample tarball, so
it could include bugs (I'm not too proficient with Make wizardry, and
the problem was not trivial to fix).  If you have time to produce a
tarball from the emacs-28 branch (the instructions are in
admin/make-tarball.txt) and then try building it, perhaps you could
test this and report any problems.  If not, I will get to that soon
enough.

The way it's supposed to work is that a special rule added in that
commit to src/Makefile.in should be triggered by the fact that the
native-lisp directory is missing in the build tree.  That special rule
is supposed to build the preloaded *.eln files (and only those), and
then re-dump Emacs.
