No, it was caused by package LazSerial...
It brings in a number of units I would not use in any console app like
this:

SysUtils, lazsynaser,  LResources, Forms, Controls, Graphics, Dialogs;

The "solution" (after googling a lot) was to add "interfaces" just
before lazserial in the uses clause of the unit that handles the
serial comm stuff:

  {$IFDEF FPC}
    interfaces, //Needed for LazSerial to work in a Console program
    LazSerial,
  {$ELSE} //Delphi

Then these linker only errors went away (compile phase worked just
fine before I did this).
