--dynamic-list isn't used to control which symbols are exported or
not.  From ld manual:

'--dynamic-list=DYNAMIC-LIST-FILE'
     Specify the name of a dynamic list file to the linker.  This is
     typically used when creating shared libraries to specify a list of
     global symbols whose references shouldn't be bound to the
     definition within the shared library, or creating dynamically
     linked executables to specify a list of symbols which should be
     added to the symbol table in the executable.  This option is only
     meaningful on ELF platforms which support shared libraries.

If you remove/change --dynamic-list, you will get the same set of
symbols in dynamic symbol table.  Please tell us exactly what you
want to see in test.so.
