bug#27581: 26.0.50; Error while compiling new Org code

[Stefan Monnier]

Package: Emacs
Version: 26.0.50


When building Emacs's master branch I get errors like:

      ELC      org/org-archive.elc
    
    In toplevel form:
    org/org-archive.el:31:1:Error: Symbol’s function definition is void: 
org-element-update-syntax
    Makefile:297 : la recette pour la cible « org/org-archive.elc » a échouée

The corresponding stack trace looks like:

    Debugger entered--Lisp error: (void-function org-element-update-syntax)
      (org-element-update-syntax)
      (if data (setcdr data (org-combine-plists (cdr data) parameters)) (setq 
org-link-parameters (cons (cons type parameters) org-link-parameters)) 
(org-make-link-regexps) (org-element-update-syntax))
      (let ((data (assoc type org-link-parameters))) (if data (setcdr data 
(org-combine-plists (cdr data) parameters)) (setq org-link-parameters (cons 
(cons type parameters) org-link-parameters)) (org-make-link-regexps) 
(org-element-update-syntax)))
      org-link-set-parameters("file+emacs")
      (progn (org-link-set-parameters "file+emacs") (org-link-set-parameters 
"file+sys"))
      (closure (org-table1-hline-regexp org-table-tab-recognizes-table\.el 
org-table-dataline-regexp org-table-any-border-regexp t) nil (progn 
(org-link-set-parameters "file+emacs") (org-link-set-parameters "file+sys")))()
      eval-after-load-helper("/home/monnier/src/emacs/trunk/lisp/org/org.el")
      run-hook-with-args(eval-after-load-helper 
"/home/monnier/src/emacs/trunk/lisp/org/org.el")
      do-after-load-evaluation("/home/monnier/src/emacs/trunk/lisp/org/org.el")
      load-with-code-conversion("/home/monnier/src/emacs/trunk/lisp/org/org.el" 
"/home/monnier/src/emacs/trunk/lisp/org/org.el" nil t)
      require(org)

So it's triggered during the evaluation of org-compat.el's after-load:

    (eval-after-load 'org
      '(progn
         (org-link-set-parameters "file+emacs") ;since Org 9.0
         (org-link-set-parameters "file+sys"))) ;since Org 9.0

There's a (declare-function org-element-update-syntax ...) in org.el but
it looks like org-element is not loaded in this case.

Not sure which is the right fix, but I do wonder why have this
eval-after-load in org-compat.el instead of simply moving the code to
org.el: eval-after-load is normally only used when we need to add code
to a file that's not under our control.
