For the record:

In configure.host, set port_specific_symbol_files accordingly.  Use whatever
linker script syntax is appropriate for the symver_map language in use.
Currently we have an extensive list of supported linkers:

  - gnu ld

Umm, yeah.  If users of other linkers want to version symbols, they'll
have to step up and write the symver map.
