  This didn't work for me, initially:

[...]
make[2]: Entering directory '/tmp/emacs-27.0-git-master/lisp'
  ELC      emacs-lisp/gv.elc
  ELC      emacs-lisp/ring.elc

  ELC      net/trampver.elc

  ELC      textmodes/css-mode.elc

In end of data:
mail/emacsbug.el:489:1:Warning: the function ‘w32--os-description’ is not
    known to be defined.
make[2]: Leaving directory '/tmp/emacs-27.0-git-master/lisp'
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.
