This is a case where I think I would prefer to see a more targeted
target hook.  Suppose we have Layout::output_section_name call a
target hook first.  If the hook returns non-NULL,
Layout::output_section can return that.  Otherwise it can apply the

Seems like the Target::output_section_name method, however it is

There should be no need for a const_cast here.
