Why not compile the object files directly into a compilation dependent
library.  Like:

lib1.a	: $(SRC)
	cc $(CFLAGS1) $? | exit
	ar a $@ $(?:.c=.o)
	/bin/rm $(?:.c=.o)

lib2.a	: $(SRC)
	cc $(CFLAGS2) $? | exit
	ar a $@ $(?:.c=.o)
	/bin/rm $(?:.c=.o)

exe1	: main.c lib1.a
	cc $(LFLAGS) -o $@ main.c lib1.a

exe2	: main.c lib2.a
	cc $(LFLAGS) -o $@ main.c lib2.a

If the compilation fails, you may get into trouble, i think the exit
will take care of this.  In general, in Sun make, this could be:

all	:	exeDEF1 exeDEF2 exeDEF3

lib%.a	: $(SRC)
	cc -c -D% $? | exit
	ar a $@ $(?:.c=.o)
	/bin/rm $(?:.c=.o)

exe%	: main.c lib%.a
	cc -o $@ main.c lib%.a
