    Use ELF_STRING_ARM_unwind in arm-tdep.c
    
    We've already has the definition like this,
    
     #define ELF_STRING_ARM_unwind           ".ARM.exidx"
    
    so it is better to use the macro rather than the string.

    	* arm-tdep.c (arm_exidx_new_objfile): Use
    	ELF_STRING_ARM_unwind.
