When I tried to help a user build tensorflow_serving on Windows, I encountered an error Cannot open compiler generated file: '': Invalid argument:

C:\tmp\_bazel_pcloudy\dpitg86y\execroot\tf_serving\external\org_tensorflow\tensorflow\core\profiler\internal\advisor\internal_checker_runner_dummy.cc : fatal error C1083: Cannot open compiler generated file: '': Invalid argument
It turns out that the object file the compiler trying to write C:/tmp/_bazel_pcloudy/dpitg86y/execroot/bazel-out/msvc_x64-py3-opt/bin/external/org_tensorflow/tensorflow/core/profiler/internal/advisor/_objs/internal_checker_runner_dummy/external/org_tensorflow/tensorflow/core/profiler/internal/advisor/internal_checker_runner_dummy.o is longer than 270 characters.
This happens when I already set the output directory to a short path C:/tmp.
