 Well, I was just trying to generate a very simple ELF64 file as an
example of what the Gujin bootloader can load from power-on.
 It would also be a Gujin regression test, i.e. check that I load
each of the segment at their right address. Gujin do not switch
to 64 bits mode, but can still understand ELF64.

 Unlike for ELF32, it seems that I cannot use the standard linker
command file to generate a valid ELF64 - i.e. something not loaded
at physical address 0 but just after the real mode address space
at 0x110000. The physical load address should be lower than the
amount of RAM a standard PC has.
 So either I need another file for the ELF64 linker, or I build
a relocatable ELF64, Gujin was able to relocate but I did not test
that for some time.
