You don't need to write this line by yourself, you just
need to provide a correct: obj-$(XXXXX) += your_module.o,
kbuild will automatically compile it with proper flags.
(If not, try CFLAGS_MODULE.)

If you insist to do this, I think you can just append
-D"KBUILD_MODNAME=your_module" to that line by hand.

Hope this helps.
