    tip(1): Fix building with -fno-common.
    
    We do so by adding 'EXTERN' to all offending variables and then defining
    'EXTERN' to 'extern' for all .c files, except for one (tip.c). This is
    the same "fix" that FreeBSD chose, to be cleaned up better at a later
    point in time.
    
    -fno-common will be default in future compilers (GCC 10, for example).
