Actually I made a mistake here. The correct patch (against the 2012
Makefile) should've just been:

-+- Makefile.orig       2016-05-27 06:51:04.862077151 +1000
+++ Makefile    2016-05-27 06:51:45.334008915 +1000
{at}{at} -13,7 +13,7 {at}{at}

 all: default

-default: nldiff$(_EXE) nlcrc$(_EXE) ulc$(_EXE) nlupdate$(_EXE)
+default: nldiff$(_EXE) nlcrc$(_EXE) ulc$(_EXE) nlupd$(_EXE)

 ifeq ($(DEBUG), 1)
   CFLAGS= -I$(INCDIR) -Ih $(DEBCFLAGS)
