python-pandas/pandas-1.3.5-pr-46681.patch
Benjamin A. Beasley b5351d82fb Run the tests (requires switching to GitHub source) 
The tests are now packaged separately in a python3-pandas+tests
subpackage, which also provides the [test] extra, since the tests—and
especially some of the associated data files that are now present to
make them actually usable—are quite large.

From 5c886169cd2674d7077271602a1a36ae0526d3ff Mon Sep 17 00:00:00 2001
From: "Benjamin A. Beasley" <code@musicinmybrain.net>
Date: Wed, 6 Apr 2022 07:13:22 -0400
Subject: [PATCH] Fix a few test failures on big-endian systems
These are all due to tests expecting little-endian dtypes, where in fact
the endianness of the dtype is that of the host.
