kbuild 2.5 deliberately does not support modversions, you can turn it
on but it does nothing. The original implementation of modversions
does not fit with the way that people build kernels now (apply patches,
change configs, rebuild without make mrproper). To do modversions
right needs a new version of modutils as well, there is no chance of
that work being started until kbuild 2.5 is in the kernel.

It works for me. menuconfig does not use include/asm-$ARCH.
