Debug doxygen generated files with different names in noarch package

[Richard Shaw]

I tried to get the subject as concise as possible :)

I'm getting consistent differences across at least two versions of zipios
and the offending arches seem to always be s390x and ppc64le.

BuildError: The following noarch package built differently on different
architectures: zipios-doc-2.2.1.0-5.fc33.noarch.rpm
rpmdiff output was:

zipios 2.2.5.0

zipios 2.2.1.0

Is this likely a big vs little endian thing?

Thanks,
Richard
