    libgloss: or1k: If available call the init for init_array
    
    There was an issue revealed in gdb testing where C++ virtual tables
    were not getting properly initialized.  This seems to be due to the
    c++ global constructors moving from ctors to init_array.
    
    This fix makes sure we call the proper method for initializing the
    constructors in all places.
