I poked around a little with a qemu s390x instance and see
the same failures.
One simple failure in t4015 is with:
git diff -w >out &&
test_must_be_empty out
Using git-2.21.0 this succeeds, while git-2.22.0-rc1 fails
and produces:
diff --git a/x b/x
index d99af23..22d9f73 100644
--- a/x
+++ b/x

I am guessing it's no coincidence that this only fails on
s390x and it is the only big endian architecture in the
fedora build system.
