From ac8673ff85fe334913382b5cabb6cf3079b91e24 Mon Sep 17 00:00:00 2001 From: Stijn Tintel Date: Fri, 30 Jul 2021 20:21:50 +0300 Subject: [PATCH] openssl: add ppc64 support Backport an upstream patch that adds support for ELFv2 ABI on big endian ppc64. As musl only supports ELFv2 ABI on ppc64 regardless of endianness, this is required to be able to build OpenSSL for ppc64be. Modify our targets patch to add linux-powerpc64-openwrt, which will use the linux64v2 perlasm scheme. This will probably break the combination ppc64 with glibc, but as we really only want to support musl, this shouldn't be a problem.
