+Subject: [PATCH v3] 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.
