A comment in 'backzone' says:

# This file is not intended to be compiled standalone, as it
# assumes rules from other files.  In the tz distribution, use
# 'make PACKRATDATA=backzone zones' to compile and install this file.

That 'make' command eventually runs something like 'zic -d 
/usr/share/zoneinfo tzdata.zii', where tzdata.zi contains the backzone info.
