Actually it is quite easy to ensure the header is within the first 8KB.
Just pad the custom-object-format-of-choice with the multiboot header.
The actual file will no longer be a standard object type, but will work.
In practice, the 8KB limitation is not severe. Nearly every OS has
a small assembly language file that ends up at the beginning of the image.
Frequently, operating system vendors put pretty little copyright notices
in this small assembly file. Adding a multiboot header is trivial.
If one must mingle the multiboot header with executable code, just add
a jmp instruction around the header.
