build/vs_toolchain.py requires find_depot_tools.py, but it's not available to a project that gets build/ via DEPS and does not also get all of tools/ via DEPS. The native_client repo needs to use build/vs_toolchain.py, but it does not copy chromium/src/tools/ and it should not have to duplicate find_depot_tools.py just to use build/vs_toolchain.py. The native_client repo also needs a standalone script to print out the depot_tools directory location, and find_depot_tools.py can serve that purpose too with some trivial additions.
