 104           code in libgcc defines them as common symbols, with the

 106           here.  If we PROVIDE the symbols then they will not be

 110           This does mean that it is not possible for a user to define
 111           their own __CTOR_LIST__ and __DTOR_LIST__ symbols; if they do,
 112           the content from those variables are included but the symbols
 113           defined here silently take precedence.  If they truly need to
 114           be redefined, a custom linker script will have to be used.
 115           (The custom script can just be a copy of this script with the
 116           PROVIDE() qualifiers added).
 117
