No...

...This is.  The Makefile is buggy -- $(LIBS) should go *after* $(OFILES).

I'm surprised the Makefile is not using the default link rule, e.g.,
something like

LDFLAGS += -L/usr/local/lib
LDLIBS += -lm -ltre
LDLIBS += -lintl -liconv
crm114_tre: $(OFILES) crmregex_tre.o
	$(LINK.o) $^ $(LOADLIBES) $(LDLIBS) -o $@

which would do the right thing w.r.t. library order, etc...
