adios2 2.11 debci tests are failing on s390x. Unit tests are passing, it's
the examples that fail, e.g.

164s Running ./hello/bpAttributeWriteRead/adios2_hello_bpAttributeWriteRead
164s /tmp/autopkgtest-lxc.sl2yynsr/downtmp/build.oVn/src/debian/tests/adios2-serial-examples: line 57:  7270 Segmentation fault         ADIOS2_PLUGIN_PATH=/usr/lib/${DEB_HOST_MULTIARCH}/adios2/serial/plugins $f 2> $f.err > $f.out
164s Error 139 in ./hello/bpAttributeWriteRead/adios2_hello_bpAttributeWriteRead
164s Field "" base type "BataD" is not a simple type or registered format name.
164s Format rejected.
164s  Field "" base type "�" is not a simple type or registered format name.
164s Format rejected.

I suspect it's an endian issue.

Hi Drew,

I can see that in the latest version of adios2 the PR
https://github.com/ornladios/ADIOS2/pull/4803 was pulled
in and also that it seems to build successfully in the buildds.

Thanks,
Pranav
