That won't work since Linux still requires the "bootblock" at 0x7d000
(or whereever that was). You only get that when using a "linux" loader.
Still, mkelfimage isn't exactly a well thought out tool. Take an ELF
linux image and add the bootblock section and you avoid a copy on
runtime and lots of complication of mkelfimage (eg. that stub it adds).
Never found the time to implement that, though.
