Hi @EricWF:

Thanks for your comment.

However, I think `OFF` is a better default for ARM (just like other platforms.)  I usually use `libc++abi` without `libunwind` since `libgcc` is quite stable and usually linked by default.  Besides, it is much more tricky to get the libc++/libc++abi/libunwind/compiler-rt combo work.  The situation goes even worse when you are linking `libgcc` together.
