I think we can use ELF-compatible format just fine, but it would make
more sense to use a non-ELF magic number from the start, instead of
signalling it with a note.  Since bootloaders need to be aware, anyway,
they can just detect this magic and treat is as an Linux calling
convention ELF image, or they can not detect it, and treat it as a
bzImage.  As a side benefit, we:

a) can use a magic number that contains a jump instruction (to keep the
non-bootsector happy);
b) get a proper Linux kernel magic number.
