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.
