It looks to me like this test is almost immediately circumvented by:

    if test "$MAKEINFO" = "no"; then
      MAKEINFO=makeinfo

configure only throws up an error message if you don’t already have
info/emacs.info in your build tree, and I’d guess Philipp has them
from before the check for 4.13 was implemented (December 2016).
