With this patch, lld creates a .note.GNU_stack and adds that to an output file if it is creating a re-linkable object file (i.e. if -r is given). If we don't do this, and if you use GNU linkers as a final linker, they create an executable whose stack area is executable, which is considered pretty bad these days.
