* config/arm/tm-arm.h: Properly define SOFTWARE_SINGLE_STEP_P.
	Always define SOFTWARE_SINGLE_STEP.
	* config/arm/tm-embed.h: Properly define SOFTWARE_SINGLE_STEP_P.
	* arm-tdep.c (arm_get_next_pc, thumb_get_next_pc, bitcount,
	shifted_reg_val): Always compile these functions.
	(arm_software_single_step): Fix second argument in function calls.
