Make doesn't know how to make .exe from .o, it's not in its built-in
rule data-base.  So you must tell it how to do that.  For example:

x.exe: x.o
	$(LINK.o) $^ $(LOADLIBES) $(LDLIBS) -o $@

(All of the $(whatever) variables used in the above are stored in
Make's built-in rule data-base; see the manual for more details.)

You could also make this rule more general by using pattern rules:

%.exe: %.o
	$(LINK.o) $^ $(LOADLIBES) $(LDLIBS) -o $@

This will make the rule work for any .o file, not just for x.o.
Again, see the Make manual for details.
