    tools/m4/list.m4: GP_LIST: Remove this because nothing uses it.
    
    I think this has not been used by any *mm projects since gtkmm-2.4
    
    We can add it back if I am wrong. And we doing new gtkmm-2.4 releases
    is hard enough anyway so there isn't much point in keeping stuff
    around just for that.
