need NOTES in vmlinux.lds.S

Without the attached patch, the current GIT trees fail to build for me
with error:

 ld: .tmp_vmlinux1: section `.text' can't be allocated in segment 0
 ld: final link failed: Bad value

This is with binutils v2.17.50.20070804 and is apparently due to the
recent --build-id changes (see
http://www.uwsg.indiana.edu/hypermail/linux/kernel/0707.2/3490.html).

I may not have picked the best possible place to stick the NOTES macro
(according to Roland, it should only be a few read-only bytes that are
hardly ever read), but at least the kernel builds again and it even
seems to boot (on my zx2000, anyhow). ;-)

Thanks to HJ Lu for his help in tracking down this bug.

[IA64] Add NOTES to linker script such that the kernel can be built with
       recent versions of binutils.  Without this patch, final link fails
       with this error:

        ld: .tmp_vmlinux1: section `.text' can't be allocated in segment 0
        ld: final link failed: Bad value

       This error is due to the fact that the --build-id option is used
       with newer linkers to include a .notes section on the kernel, but
       without the NOTES macro, that section won't be included in the kernel
       which then leads to the above error message.
