Solved:
I found the source for a kernel module on the net:


and dug out the Makefile I used for the same module on an RPI2:

Makefile:
obj-m := perf.o

all:
        $(MAKE) -C /lib/modules/$(shell uname -r)/build M=$(PWD)
modules

clean:
        $(MAKE) -C /lib/modules/$(shell uname -r)/build M=$(PWD) clean

which produced a nice kernel module.
