In drivers/Makefile it is wrongly assumed that there are no KBUILD_OUTPUT:

kernel-ver::
       $(CC) -I$(KERNEL_DIR)/include -o $@ $@.c


$(KBUILD_OUTPUT)/include should be used instead of $(KERNEL_DIR)/include when
KBUILD_OUTPUT is set.

thank you, I fixed it in the ebuild by using KV_OUT_DIR instead of KV_DIR
