Dear Maintainer,
buildd reports failing unit tests on s390x and ppc64: [1] [2]

Some debugging reveals that this error happens due to mismatched endianness
when reading data files.

It's likely that there are many more similar problems lurking in the source
code.
If this issue can't be fixed, the package should probably be disabled on big
endian architectures.
Thanks!
