+# gcc bug http://gcc.gnu.org/PR63341 in ppc code generation requires
-fno-tree-vectorize for now
+ARCHFLAG/ppc     += -fno-tree-vectorize
+ARCHFLAG/ppc64   += -fno-tree-vectorize
+ifeq ($(TYPE),ZERO)
+  ifeq ($(ZERO_ARCHDEF),PPC)
+    ARCHFLAG/zero += -fno-tree-vectorize
+  endif
+  ifeq ($(ZERO_ARCHDEF),PPC32)
+    ARCHFLAG/zero += -fno-tree-vectorize
+  endif
+  ifeq ($(ZERO_ARCHDEF),PPC64)
+    ARCHFLAG/zero += -fno-tree-vectorize
+  endif
+endif

We should limit this workaround to versions of GCC < 5 at the minimum.
