    PR29846, segmentation fault in objdump.c compare_symbols

    Fixes a fuzzed object file problem where plt relocs were manipulated
    in such a way that two synthetic symbols were generated at the same
    plt location.  Won't occur in real object files.

            * objdump.c (compare_symbols): Test symbol flags to exclude
            section and synthetic symbols before attempting to check flavour.
