    Re: dlltool memory leaks
    
    I missed one needed strdup of symbol names, needed since the original
    symbol name memory is freed on bfd_close.
    
            PR 33651
            * dlltool.c (scan_filtered_symbols): xstrdup symbol name.
    
    (cherry picked from commit d37a8694b28d162c5e0ed0edd5948687bc228edc)
