This revision now requires changes to proceed.

The NATIVE build is also used for cross-compilation scenarios (e.g. you're building on Windows but targeting Linux, but you still need tools like tablegen to be built targeting Windows), and for those cases, using the same CMAKE_TOOLCHAIN_FILE as the main build is completely incorrect.

What I've done to handle situations like this is set the `CROSS_TOOLCHAIN_FLAGS_NATIVE` cache variable to include the desired toolchain file for the NATIVE build (and any other desired CMake settings as well). Does that work for you? Something like `-DCROSS_TOOLCHAIN_FLAGS_NATIVE="-DCMAKE_TOOLCHAIN_FILE=/path/to/your/toolchain/file"` should do the trick.
