"builtin" is not a standard UNIX System V Bourne shell feature.  It is
found in the 8th and 9th Edition UNIX shells, in the BRL SVR2 Bourne
shell, and possibly (I'm not sure) in the Korn shell.  In fact, it
isn't useful in standard SVR2 Bourne shells, because they don't permit
defining functions that have the same name as built-ins.  (However,
you could define a "ch" function and get used to typing "ch wherever"
to change directory.)  SVR1, 4.nBSD, and other older shells don't
support definition of shell functions at all.
