m68k.c, m68k.md (SGS, [...]): Remove code to support SGS assembler. 

	* config/m68k/m68k.c, config/m68k/m68k.md (SGS, SGS_CMP_ORDER): Remove
	code to support SGS assembler.  Reformat adjacent code where possible.
	* config/m68k/m68k.c (switch_table_difference_label_flag): Remove definition.
	* config/m68k/m68k.h (PRINT_OPERAND_PUNCT_VALID_P): Remove support for '%#'.
	* config/m68k/linux.h, config/m68k/m68k.c,
	* config/m68k/math-68881.h: Replace `%#' with `#' in inline asm macros and
	asm_printf() format strings.
	* config/m68k/m68kelf.h (ASM_OUTPUT_CASE_END): Remove macro definition.
	* config/m68k/linux.h: Update copyright.
	* config/m68k/linux.h, config/m68k/m68k.c: Remove traling whitespace.
