Ah!

The .notes section gets SHT_NOTE in vmlinux when xen-head.S is included;
PROGBITS when linked.  I tried putting @note on the .section in
linux/elfnote.h, but that didn't seem to help (xen-note.o got a SHT_NOTE
entry, but it didn't make it into vmlinux).  I couldn't see any way of
forcing the section type in vmlinux.lds; my experiments all ended with
ld dumping core.
