CHRP does not want just an ELF image, but an ELF image with a CHRP
"note" section. The note section describes where to load the image,
whether the image is running real or virtual, and how to instantiate OF.
NetBSD has more details about this for their macppc port. Cort may
already have addressed some of this for the CHRP-based RS/6000 port work.
CHRP looks for a PT_NOTE section in the loader header and then
specific magic values in the section itself.
