I think you'll find objdump on your resulting binary much, much 
faster :)

I have the following makefile rules too (BSD make though)..

CPPFLAGS+=-Wa,-adhlmsn=${<:T:S/.c/.lst/}
LDFLAGS+=-Wl,-Map=${PROG}.map,--cref

.elf.dmp:
        ${OBJDUMP} -S ${.IMPSRC} > ${.PREFIX}.dmp

This gives you a lot of information about how the compiler has decide to 
build your code.
