I have no idea where your problem might be coming from but I'm guessing it might be missing the "M" argument.
i.e. $(PYTHON) modsilent.py $(MAKE) KBUILD_EXTRA_SYMBOLS=$(moduledir)/Module.symvers -C $(KERNELDIR) M=$(PWD) CC=$(CC) V=$(BUILD_VERBOSE) modules For the record, I have been able to build and run LinuxCNC against RTAI GNU11 and the new libm-kbuild branch by doing a classic ./configure rip install. Your problem must be stemming from the debian/ directory in LinuxCNC. As a sanity check, have you done the same to ensure your RTAI environment is all good? Just a quick run-in-place install for testing.
