Add a few required defines to support using the binfmt_elf_fdpic loader on the m68k architecture. The values are defined to be consistent with those used on arm and sh which support this too. The most important m68k specific change is the register initialization. The pt_reg structure only contains a subset of the architecture general registers, so we are more limited than to be expected on what can be used.
