I would just set all this stuff at the global scope rather than overriding
ConfigureStep.

+
+  DefaultConfigureStep
+}
+
+SetOptFlags() {
+#tor doesn't like NDEBUG, thus avoiding it for now
+  if IsCMakeProject; then
+    return
+  fi
+
+  if [ "${NACL_DEBUG}" = "1" ]; then
+    NACLPORTS_CFLAGS+=" -g -O0"
+    NACLPORTS_CXXFLAGS+=" -g -O0"
+  else
+#    NACLPORTS_CFLAGS+=" -DNDEBUG -O2"
+     NACLPORTS_CFLAGS+=" -O2"
+#    NACLPORTS_CXXFLAGS+=" -DNDEBUG -O2"
+     NACLPORTS_CXXFLAGS+=" -O2"
+    if [ "${NACL_ARCH}" = "pnacl" ]; then
+#     NACLPORTS_LDFLAGS+=" -DNDEBUG -O2"
+      NACLPORTS_LDFLAGS+=" -O2"
+    fi
+  fi
+}
+
+BuildStep() {
+ SetOptFlags
+ DefaultBuildStep

Probably cleaner to do it removing the NDEBUG (see ports/grep/build.sh)
