I would say:

    choice
           prompt "ARM instruction set"
           default BR2_ARM_INSTRUCTIONS_ARM if BR2_ARM_CPU_HAS_ARM
           default BR2_ARM_INSTRUCTIONS_THUMBS2 if BR2_ARM_CPU_HAS_THUMBS2
           default BR2_ARM_INSTRUCTIONS_THUMBS if BR2_ARM_CPU_HAS_THUMBS

Best regards,
Benoît
