It's referring to this section of code.  Note the placement of the 
#endif.  Looks weird, not sure if it's in the right place, should be a 
line earlier or a line later:

#if ARM_UNWIND_INFO
#undef TARGET_ASM_UNWIND_EMIT
#define TARGET_ASM_UNWIND_EMIT arm_unwind_emit

/* EABI unwinding tables use a different format for the typeinfo tables.  */
#undef TARGET_ASM_TTYPE
#define TARGET_ASM_TTYPE arm_output_ttype

#undef TARGET_ARM_EABI_UNWINDER
#define TARGET_ARM_EABI_UNWINDER true

#undef TARGET_ASM_EMIT_EXCEPT_PERSONALITY
#define TARGET_ASM_EMIT_EXCEPT_PERSONALITY arm_asm_emit_except_personality

#undef TARGET_ASM_INIT_SECTIONS
#endif /* ARM_UNWIND_INFO */
#define TARGET_ASM_INIT_SECTIONS arm_asm_init_sections
