If you want all the files to be rebuilt every time, why use make at all?
Just write a shell script.

Well, you can either use ifeq () with the $(MAKECMDGOALS) variable, or,
if you have a sufficiently recent version of GNU make, you can use a
target-specific variable attached to the asm target:

    asm: EXTRA_FLAGS = -S -fverbose-asm
    asm: $(ASMSRC:%.c=%)

or similar.


See the GNU make manual for descriptions of both of these features.
