Log message:
Added code to change the default W (width) bit based on whether the
kernel being loaded is som/elf32 (narrow) or elf64 (wide).

THE KERNEL IS STILL LAUNCHED IN NARROW MODE -- BEWARE TRASH IN THE
UPPER HALVES OF ARGUMENT REGISTERS ONCE 64-bit IS ENABLED!  Since
there are only 4 args passed to the kernel, the wide/narrow calling
convention difference shouldn't be a problem, especially since head.S
is assembly code and sets up its own world anyway.
