This is a 32-bit operating system. pg_basebackup does not use whatever features are in libz for dealing with files larger than 4Gb on a 32-bit operating system, so that's your issue right there.
How did you find yourself with a 32-bit operating system in 2017? I think the general idea when we built that into pg_basebackup was that nobody with anything that big would be running a 32-bit operating system those days, and certainly not now..
Your workaround for that is to make pg_basebackup write to stdout, and use an external gzip in a pipe.
