    newlib: info: tweak iconv node to avoid collisions
    
    We have "Iconv" and "iconv" nodes which generates Iconv.html and
    iconv.html files.  On a case-insensitive filesystem, these collide.
    Rename the "Iconv" node to match the chapter name that it's already
    using to avoid the issue.
