Approved and applied.

Note - I made two minor changes:

  1. I renamed 'is_unwind_section_name' to 
'is_arm_elf_unwind_section_name' in order to make it clear that it is an 
arm-elf specific function.

   2. I used the ChangeLog in the include/elf subdirectory for the 
change to the arm.h header file, rather than the ChangeLog in the 
include/ directory.

Cheers
