The patch is created for the maint branch.

I have reordered some part of the quoted message.

org-agenda.el (and some other files) should be fixed anyway.

make single
Compiling single /home/ubuntu/org-mode/lisp/org-agenda.el...

In end of data:
org-agenda.el:10769:1:Warning: the function ‘string-empty-p’ is not known to
     be defined.

(log for emacs-25.2.2)

I just do not have enough experience with elisp to suggest a patch to 
explicitly notify users that they have mixed org install. On the other 
hand, particular symptom from the report can be easily mitigated.

There is the only place in org where `string-empty-p' is used. There is 
no (require 'subr-x) in org-agenda.el. Notice

lisp/org.el:10: ;; Package-Requires: ((emacs "24.3"))

Till this line is updated, I suppose, patches should respect it, 
especially for the maint branch. Unfortunately new org cite feature 
recently merged to master relies on some rx features unavailable even in 
Emacs-26.3 (Ubuntu-20.04 LTS focal).

It seems, RedHat-7 and thus CentOS-7 were released with Emacs-24.3. I 
have no idea how many users run these flavors on desktops and are 
permitted to update Org to the latest version. Accordingly to
end of lifetime dates for CentOS-7 are 2020-08-06 for full updates and 
2024-06-30 for maintenance updates.
