So appearantly kbuild thinks you have a vmlinux
so no need to relink.
And the line "LINK linux" implies this as well.

Please double check that you do not have a vmlinux,
and try V=2" to see where LINK picks up the vmlinux.

My build finised:
$ ./linux
./linux: /usr/lib/libc.so.1: bad ELF interpreter: No such file or directory

So I will take an additional look tomorrow.

Sam
