[Bug 1602655] Re: The openssl s390x assembly pack is not used

[Dimitri John Ledkov]

Some updates on this ticket: openssl-1.1 in debian experimental has asm
optimisations enabled for the debian-s390x build configuration. Enabling
similar configuration change in 1.0.2 results in the package failing to
build from source - shared libraries appear to be missing for an unknown
reason. Investigating further.
