I did a clean pull from 'master' ( commit id:
b87c874aa1016939ccbee4cd3bd1384726cb2220 ), followed by './configure
--with-x-toolkit=gtk3 --with-xwidgets --with-modules; make' and I get:

make -C ../lisp compile-first EMACS="../src/bootstrap-emacs"
make[2]: Entering directory '/home/deech/emacs/lisp'
make[2]: Nothing to be done for 'compile-first'.
make[2]: Leaving directory '/home/deech/emacs/lisp'
make[2]: Entering directory '/home/deech/emacs/lisp'
  ELC      ../lisp/files.elc

It's a known problem. Work around it with 'make bootstrap'. See:

A much simpler and shorter recipe is to rename .dir-locals.el before
building, then rename it back after the build.

FWIW, I tried to track the origin of the problem but still failed to
find it.  It looks like

    rm lisp/emacs-lisp/gv.elc; make

"fixed" it this time (the error was signaled while macroexpanding
a (setf (alist-get ...) ...) in hack-dir-local-variables which ended up
(auto)loading gv).

  This didn't work for me, initially:

[...]

make[1]: Leaving directory '/tmp/emacs-27.0-git-master/lisp'
 

      This error occurred on Gnu/Linux.

      When I did another "git pull; make" to go to git hash 73ba6f1
      from 913c001 it then compiled.to completion.

      BTW, why is the message:

           Reloading stale loaddefs.el

      emitted?

      What's the significance of specifying "stale"?
      
      Is it just informational?
      
      Thanks.

I don't see any error in the text you quoted.

This message means that the `(bootstrap-)emacs` executable used to
byte-compile "that" file was built at a time when loaddefs.el was
different, so before performing the compilation we reload loaddefs.el to
overwrite the preloaded settings with its new contents.

IOW the "stale loaddefs.el" is the one that was preloaded rather than
the current file.

I guess it wasn't a great choice of word, indeed, since it makes it
sound like the current loaddefs.el is stale.

  Indeed it's a warning, sorry.

  The "error" (warning) I am referring to is the fact that
  ‘w32--os-description’ is being reference at all (and if/when
  referenced, the "w32-fns.el" file should have been or caused
  to beloaded).

  Is it because it's not necessary during the dump process?

  Thanks.

Should be fixed now, thanks.

It's because gv.elc uses circular syntax, and files.el was binding
read-circle to nil around there. Should be fixed in master now.
