Ensure we call into the host C library open/close/read/write independently of which embedded C library the code is built with. We do this by: a) Using the native simulator nsi_host* trampolines when we just want to call straight into the host libC. b) Building in the native_simulator runner context (and therefore with the host C library) two functions which we call from the embedded side.
