File openssl-s390x-assembly-pack-add-OPENSSL_s390xcap-environment.patch of Package openssl-1_1
From f39ad8dcaa75293968d2633d043de3f5fce4f37b Mon Sep 17 00:00:00 2001 From: Patrick Steuer <patrick.steuer@de.ibm.com> Date: Mon, 30 Jan 2017 17:37:54 +0100 Subject: [PATCH] s390x assembly pack: add OPENSSL_s390xcap environment variable. The OPENSSL_s390xcap environment variable is used to set bits in the s390x capability vector to zero. This simplifies testing of different code paths.
