+remove a duplicate dependency
+
+Upstream-status: Pending
+
+The install-rb-default dependency is as below:
+
+pre-install-rb-default:
+	mkdir -p $(RUBYLIBDIR)/bigdecimal
+
+install-rb-default: pre-install-rb-default $(RUBYLIBDIR)/bigdecimal
+
+In fact, dependency on $(RUBYLIBDIR)/bigdecimal is duplicate, and not rule
+for $(RUBYLIBDIR)/bigdecimal, once $(RUBYLIBDIR)/bigdecimal is checked before
+pre-install-rb-default, the below error will happen
+	*** No rule to make target `../../.ext/common/yaml', needed by `install-rb-default'.  Stop
