    Fix spurious match in extract_symvers
    
    Tighten the regex to find the start of the .dynsym symtab in the readelf
    output to avoid matching the section symbol in the normal symtab.
    
    libstdc++-v3:
            * scripts/extract_symvers.in: Require final colon to only match
            .dsynsym in the header of the dynamic symtab.
