* config/m68k/m68k.h (REGISTER_MOVE_COST): Simplify definition.
(STACK_GROWS_DOWNWARD): Define to 1.
(FUNCTION_VALUE, LIBCALL_VALUE, FUNCTION_VALUE_REGNO_P): Equivocate
comments, emphasizing that these values are only defaults.
* config/m68k/linux.h (LINK_SPEC): Fix formatting in #undef.
* config/m68k/m68k.c (const_method): Remove trailing whitespace.
