    Update the section on binutils version
    
    LTO usage requires binutils 2.35 or newer due to
    https://sourceware.org/PR25355.
    This adds a note in the prerequisites page about it.
    
    Ok?
    
    gcc/ChangeLog:
    
            * doc/install.texi: Add note about
            binutils 2.35 is required for LTO usage.
