    Move the initial debug_hooks setting
    
    I just realized that when I moved the langhook call I failed to
    move the initial debug_hooks setting whose comment mentions the
    langhook as reason.

            * toplev.c (process_options): Move the initial debug_hooks
            setting ...
            (toplev::main): ... before the call of the post_options
            langhook.
