It's not really an a.out file, but it contains section information in
the multiboot header that allows it to to be loadded successfully.
Normally, this feature is used to load a.out file in a platform
independent way, as the a.out header is not quite reliable. In the
case of core.img, there is no a.out header at all, but the section
information is inside the multiboot header.
