	* config/m68k/m68k.h (ASM_CPU_SPEC, ASM_SPEC, EXTRA_SPECS)
	(SUBTARGET_EXTRA_SPECS): New macros.
	* config/m68k/linux.h (ASM_SPEC): Remove CPU flags;
	use %(asm_cpu_spec) instead.
	* config/m68k/m68k-none.h (ASM_SPEC): Likewise.
	* config/m68k/openbsd.h (ASM_SPEC): Likewise.
	* config/m68k/netbsd-elf.h (ASM_SPEC): Likewise.
	(EXTRA_SPECS): Rename to...
