[v3] Export std::_List_node_base for non-PIC code

[Rainer Orth]

As discussed in PR libstdc++/52689, no longer exporting
std::_List_node_base for non-PIC code breaks linking go1 on Solaris with
static libstdc++:

Undefined                       first referenced
 symbol                             in file

ld: fatal: symbol referencing errors. No output written to go1

The following patch fixes this, bootstrapped without regressions on
i386-pc-solaris2.11, approved by Benjamin in the PR, installed on
mainline.
