Thank you for reporting. I confirmed what you reported.

Looking at auctex.el in ELPA repository[1], it still has
;; Package-Requires: ((emacs "25.1"))
in the header. I suppose this is the culprit.

It seems that the change in auctex.el.in didn't propagate to auctex.el.
Tassilo, shouldn't the GNUmakefile[2] have a rule to generate auctex.el
from auctex.el.in? (Maybe that causes discrepancy in the copyright
header of the generated auctex.el diverging from what ELPA system
expects?)
