    Fix "Too many levels of symbolic links" in chapter 8 ncurses
    
    The problem is that TIC_PATH is nor honored anymore in chapter
    6, so that tic from the host is used to create the terminfo
    database in chapter 6. The problem is that old versions of
    tic create symlinks in the database, while newer versions
    create hardlinks. Since we use a DESTDIR install in chapter 8
    (with a recent version of ncurses, so with hardlinks), and copy
    it in place with cp -a, then it seems that copying hardlinks to
    symlinks. If an old version of tic has been used in chapter 6,
    this copies hardlinks to symlinks, which creates symlinks
    pointing to themselves (cp bug?).
    
    Anyway, the solution is to copy the auxilliary tic built
    in chapter 6 to $LFS/tools/bin (suggestion by Xi Ruoyao).
    Now, there is no need to set TIC_PATH or whatever because this
    tic is in the PATH.
    
    Bug first reported by Marcin Dulak. Analysis with the help of
    Bruce Dubbs and Thomas Trepl.
