[LLVMdev] tools build issue with lnt in cross platform testing

[Reed Kotler]

The issues seems to be this line in the tools Makefile

timeit-target: timeit.c
	$(LD_ENV_OVERRIDES) $(LCC) -o $@ $< $(LDFLAGS) $(CFLAGS) 
$(TARGET_FLAGS) -O3

It should not add target flags if we are simulating the target on the host.
