No, 33721 is about stack variables and not static allocated variables which
still is limited by the linker.

That is because it is limited not by the GNU ld but rather the file formats
that are in use for the target (or non GNU linkers). So I think the
documentation is still correct in what is says, it just needs to cleared up
slightly and also talked about stack allocated variable which have no linker
issue involved.
