make: *** [kaldi_pybind.cpython-37m-x86_64-linux-gnu.so] Error 1

Start by reproducing the make target for kaldi_pybind.cpython-37m-x86_64-linux-gnu.so and inspect the linker diagnostic for CuDevice::this_thread_device_ being defined as both __thread and non-__thread. Done means the pybind11 shared library links successfully without this symbol conflict.
