[PATCH 450] M68k new gcc

[Geert Uytterhoeven]

M68k: Fixes for when compiling with modern gcc (from Roman Zippel):
  - Avoid warning 'use of memory input without lvalue in asm operand 0 is
    deprecated' of newer gcc
  - Replace some '%/' with offical '%%' to escape a '%'

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
