Not necessarily; the system might have a more up-to-date tzdata.

Generally you'd use --with-system-tzdata on a platform where you expect
to receive routine package updates for the tzdata files, independently
of the Postgres release cycle. It seems reasonable to assume that
anyone currently shipping tzdata is offering 64-bit files. (But we do
have that regression test check in there to make sure.)
