alpha: Fix bootpfile and bootpzfile make targets
Fix the bootpfile and bootpzfile make targets to creat BOOTP images. Both targets were broken due to some missing defines to re-map ELF constants. In addition the old code used the generic vsprintf function of the kernel which we now replace by a simple and much smaller implementation for the bootloader.
