The patch generally makes sense to me.

I wonder if the test configuration can also benefit from this; `test/libcxx/test/target_info.py` manually updates the link line to use `-lgcc_s` or `-lunwind` depending on how the build is configured. Presumably, this workaround will no longer be needed if the linker script does that for us?

(Note:- `-lgcc_s` is linked twice there to satisfy some weird dependency, it's not a mistake)
