I don't know if this is worth a send-pr, at least not until the cause is
explained better, but I find this kind of curious.

$ cd /usr/src/lib
$ make -n 
[[....]]
all ===> librpcsvc
make: don't know how to make set. Stop

make: stopped in /work/woods/NetBSD-src/lib/librpcsvc
*** Error code 2

Stop.
make: stopped in /work/woods/NetBSD-src/lib
$ fgrep set librpcsvc/Makefile
# This little dance is necessary because RPCGEN doesn't get set until
        @set -- X `type ${RPCGEN}` && shift `expr $$# - 1` && echo "$$1"
$ cd librpcsvc
$ make -n
$ echo $RPCGEN
