It's peculiar that you have a mix of /usr/src and /usr/home/nk/src.
Looking at /usr/src/Makefile.inc1 it would appear that you may also
have to set KRNLOBJDIR to /usr/home/nk/src/kernel/src.
Does the tmp directory really exist? Seems like a weird choice.
I did what Ryan suggested and was able to make build{kernel,world}
from /usr/src with no problem. But I haven't modified the kernel
sources.
