+From 9e4f30b3168a95243df0c0891e3e432bc95382ad Mon Sep 17 00:00:00 2001
+From: Lauri Kasanen <cand@gmx.com>
+Date: Mon, 1 Jun 2020 12:11:45 +0300
+Subject: [PATCH v2] Bug 1642174 /usr/bin/ld: OBJS/Linux_SINGLE_SHLIB/sha512-p8.o:
+ ABI version 2 is not compatible with ABI version 1 output
+
+Don't try to build the SHA-2 accelerated asm on old-ABI ppc.
+
+Currently make only, I don't have enough gyp-fu to do that side.
+However, the reporters of 1642174 and 1635625 both used make, not gyp.
