They're not needed on systems that have tm_gmtoff and tm_zone, as
strftime can and should consult those struct tm members instead of
consulting any separate timezone_t type.
Systems that lack tm_gmtoff and tm_zone can't possibly be thread-safe in
the presence of multiple time zones anyway, so we don't need to worry
about adding strftime_z and strftime_lz to such systems.
