* config/arm/arm.opt (arm_arch_specified, arm_cpu_specified,
arm_tune_specified): New TargetVariables.
* config/arm/arm.c (arm_configure_build_target): Comment out
opts_set argument name. Use opts->x_arm_*_specified instead
of opts_set->x_arm_*_string.
* common/config/arm/arm-common.c (arm_handle_option): New function.
(TARGET_HANDLE_OPTION): Redefine.
