If we do that we need to document what the new way of doing "just load
and jump to the entry point of my not-a-linux-kernel ELF image" is; at
the moment for ARM that use case is supported by -kernel (the code
specifically handles ELF images as not-kernels), so changing that would
be a back-compatibility break...
(maybe this should be '-bios' but that seems a bit of an obscure name.)
