Right. The problem is on configure in fact. I should have reported that the
autotools files were out-of-date, other than just config.*. Sorry.

Yes. The problem is that configure doesn't know about ppc64el, and dh_autoreconf
fixes it (with many other libtool configuration).
So, if you run dh_autoreconf, this is the 'patch' that is added on top of

Causing the 'ld -m' to check for the little endian architecture, other than just
elf64ppc (which is wrong).
