Thanks, that did the trick, resulting Makefile:

obj-m := ctracer.o

ctracer-y := ctracer_methods.o ctracer_jprobe.o

# Files generated that shall be removed upon make clean
clean-files := ctracer_methods.c

CLASS=sock
KDIR := /lib/modules/$(shell uname -r)/build
PWD := $(shell pwd)

default:
        $(MAKE) -C $(KDIR) SUBDIRS=$(PWD) modules
clean:
        rm -f *.mod.c *.ko *.o ctracer_methods.c

$(obj)/ctracer_methods.o: ctracer_methods.c

$(src)/ctracer_methods.c:
        ctracer /usr/lib/debug/lib/modules/$(shell uname -r)/vmlinux 
$(CLASS) > $@
