While working on something else, I noticed that there are still some
CONFIG_IA64_EARLY_PRINTK bits left over in head.S, even though that
option is long gone (replaced by console=uart etc.)

While at it, I also added a "hint @pause" in the endless loop at the
end of _start.  Not that it ever should get executed, but if it ever
does, why waste power/cycles?
