Note that both are big endian. All others (little endian) pass.

The failure is the same:

-found symbol 'foo', an instance of function symbol type of global binding, of versions 'VERSION_2.0', 'VERSION_1.0'
+could not find symbol 'foo' in file '/home/mjw/bb/wildebeest/libabigail-fedora-s390x/build/tests/data/test-lookup-syms/test1.so'
FAIL runtestlookupsyms (exit status: 1)

And it happened after:

commit e0950e64279d59e92de5170d805be99f84cdfd8d

    dwarf-reader: Use all bits of Bloom filter words.

Staring at the code it might certainly be that some words are swapped
in the big-endian case, but I am not seeing it (nor do I really
understand the whole algorithm, so...)

Cheers,
