[oe] Does it possible to use pre-built native tools

[Guo Hongruan]

Hi frans,
   In fact, I need to build completely different images for different  
architecture in different tmp directories. We need to do nightly build on  
build machine. So I think it would be better for several builds using the  
same one native tools set. It does not need to build native tools from  
zero on every time.
