My guess would be that you've run one of the previous builds as root and
now when you run it as normal user there is not enough permissions to
modify some files.

Try checking who owns the file init/.version.o.d using 'ls -l' and if the
owner is root change the ownership for the entire kernel directory with 

sudo chown -R $USER .

You may also try running 'sudo make mrproper' to wipe the files generated
during previous builds and then start over from clean slate.
