Random s390x build failures

<a href="https://bugzilla.redhat.com/show_bug.cgi?id=1734883" title="https://bugzilla.redhat.com/show_bug.cgi?id=1734883">https://bugzilla.redhat.com/show_bug.cgi?id=1734883</a>

Builds fail semi-randomly on s390x. The symptom is the tarball fails
to unpack properly:

DEBUG util.py:585: BUILDSTDERR: error: unpacking of archive failed on file /builddir/build/SOURCES/otp-OTP-22.0.7.tar.gz;5d725d41: cpio: read failed - Inappropriate ioctl for device
DEBUG util.py:585: BUILDSTDERR: error: /builddir/build/originals/erlang-22.0.7-1.el8.src.rpm cannot be installed

Rerunning the build is normally sufficient to work around the problem,
but I wonder if anyone has any clue about this bug? Seems like it's a
problem in librpm, cpio or the s390x kernel, but why would it be random ...

I've got a couple of loops running over and over again on a real
Fedora/s390x[1] server unpacking the tarball and the srpm respectively
and neither one appears to fail at all.

Rich.
