    string merge section map output
    
    This fixes an inconsistency in the linker map file, where string merge
    sections (other than the first) kept their sizes.  String merge
    sections of like entsize all are accounted in the fisrt string merge
    section size.
    
            * ldlang.c (print_input_section): Print SEC_EXCLUDE section size
            as zero.
