See below.

Why ? GCC has knowledge only of .o files, not .obj files.

This is what I use inside my makefiles. It's simple, and works !
(The only limitation is that you have to have a separate 
directory for each program you want to compile and link.)

OBJS = a.o b.o c.o d.o e.o f.o g.o

prog.lnk: $(OBJS)
        -del prog.lnk
        for %o in (*.o) do echo %o >>prog.lnk   # MS-DOS batch language

prog: prog.lnk
	cc -o prog @prog.lnk -lm
