Your Makefile is essentially in the form:

all: lib.a(obj.o)
	: make objects
	: put objects in library
	ranlib

but make already knows the dependencies (internally)

lib.a(obj.o): obj.o
obj.o: obj.c

so make will update this object by CC and AR'ing for you if
it finds the obj.c.

Therefore the make objects and ar objects lines are not necessary.
You can see what built in rules your make has by invoking make -np.
