Description

In the file: tensorflow/lite/micro/kernel/xtensa/logistic.cc, line 88, calling xa_nn_vec_sigmoid_asym8s_asym8s() function.
But in make file: tensorflow/lite/micro/tools/make/ext_libs/xtensa.inc, line 117, it removed xa_nn_activations_asym8_asym8.c containes xa_nn_vec_sigmoid_asym8s_asym8s() define.
So, I do not know whether this file should be included.
