Shouldn't there be a continuation "\" in:

#   $NetBSD: Makefile,v 1.128 1999/11/05 11:31:40 mycroft Exp $

at:

distrib-dirs:
    ${INSTALL} ${INSTPRIV} -d -o root -g wheel -m 755 ${DESTDIR}
    -mtree -def mtree/NetBSD.dist -p ${DESTDIR}/ -u
    cd ${DESTDIR}; rm -f sys; ln -s usr/src/sys sys

(given that "-mtree ..." doesn't execute very usefully) shouldn't it be:

distrib-dirs:
    ${INSTALL} ${INSTPRIV} -d -o root -g wheel -m 755 ${DESTDIR}  \
	-mtree -def mtree/NetBSD.dist -p ${DESTDIR}/ -u
	cd ${DESTDIR}; rm -f sys; ln -s usr/src/sys sys
