Test CPP fails to build (possibly typo)

Downloaded 0.9.1 and tried to build, it failed at

Makefile:832: warning: overriding commands for target `gen-cpp/ThriftTest.cpp'
Makefile:829: warning: ignoring old commands for target `gen-cpp/ThriftTest.cpp'
/bin/bash ../../libtool --tag=CXX --mode=link g++ -Wall -g -O2 -L/usr/lib -o libtestgencpp.la ThriftTest_constants.lo ThriftTest_types.lo ../../lib/cpp/libthrift.la -lssl -lcrypto -lrt -lpthread

A close inspection to the Makefile, lines 829 and 832 show:

gen-cpp/ThriftTest.cpp gen-cpp/ThriftTest_types.cpp gen-cpp/ThriftTest_constants.cpp: $(top_srcdir)/test/ThriftTest.thrift
$(THRIFT) --gen cpp:templates,cob_style -r $<

gen-cpp/ThriftTest.cpp gen-cpp/StressTest_types.cpp gen-cpp/StressTest_constants.cpp: $(top_srcdir)/test/StressTest.thrift
$(THRIFT) --gen cpp $<

because a rule for gen-cpp/ThriftTest.cpp is defined twice, the compiling process breaks. The following patch fixes it
