  Log:
  Enable the i386 loader to load and run an amd64 kernel.  If this puts
  things over floppy size limits, I can exclude it for release builds or
  something like that.  Most of the changes are to get the load_elf.c file
  into a seperate elf32_ or elf64_ namespace so that you can have two
  ELF loaders present at once.  Note that for 64 bit kernels, it actually
  starts up the kernel already in 64 bit mode with paging enabled.  This
  is really easy because we have a known minimum feature set.
  
  Of note is that for amd64, we have to pass in the bios int 15 0xe821
  memory map because once in long mode, you absolutely cannot make VM86
  calls.  amd64 does not use 'struct bootinfo' at all.  It is a pure loader
  metadata startup, just like sparc64 and powerpc.  Much of the
  infrastructure to support this was adapted from sparc64.
