I think the missing file belongs to the source code for linux, not linuxcnc.
try looking at
https://github.com/torvalds/linux/blob/master/include/asm-generic/asm-offsets.h
you may need both bodies of code avaialable to compile OpenCN
I do not see that file in my local builds ( run-in-place builds) of
linuxcnc.

Dear OpenCN developers,
Could you please help with OpenCN build problems.
First steps have done without issues:
$ cd opencn/rootfs $ make opencn_x86_defconfig $ make
but after that I have got an error:
root@OpenCN-2:~/opencn/rootfs# cd ../usr/
root@OpenCN-2:~/opencn/usr# ./build.sh
