Yes this is the root cause of failure:

/usr/bin/ld: /usr/lib/powerpc64le-linux-gnu/libadplug.so: undefined

The ABI mismatch can be verified using ELF attributes:
root@sbuild:/build/reproducible-path# readelf --arch-specific
/usr/lib/powerpc64le-linux-gnu/libbinio.so | grep Tag_GNU_Power_ABI_FP
Tag_GNU_Power_ABI_FP: hard float,
128-bit IEEE long double
root@sbuild:/build/reproducible-path# readelf --arch-specific
/usr/lib/powerpc64le-linux-gnu/libadplug.so | grep Tag_GNU_Power_ABI_FP
Tag_GNU_Power_ABI_FP: hard float,
128-bit IBM long double
So:
libbinio is built with IEEE long double ABI and libadplug is built with
IBM long double ABI
These ABIs are binary incompatible, so reverse dependencies cannot link
both libraries together.
A rebuild of libadplug on ppc64el should resolve the issue.
Thanks and Regards,
