I eman what I said: you need to use the target (4.x) version of
release/Makefile*, and /usr/src matching your running world and
kernel (5.x).  WORLDDIR is not supported by 4.x release/Makefile,
hence the sequence above.

You need Perl because 5.x doesn't have Perl in the base system,
hence initial "make installworld" (which will install 5.x world
into ${CHROOTDIR}) will not install Perl needed to build a 4.x
kernel.
