tensorflow lite shared libary build...

需要在android上，通过.so的方式，基于c++调用 tensortflow lite 的函数。
如何实现.so的编译呢？？步骤如下：

add this to BUILD file in contrib/lite

cc_binary(
name = "libtensorflowLite.so",
linkopts=["-shared", "-Wl"],
linkshared=1,

copts = tflite_copts(),
deps = [
    ":framework",
    "//tensorflow/contrib/lite/kernels:builtin_ops",
],
)

bazel build //tensorflow/contrib/lite:libtensorflowLite.so --crosstool_top=//external:android/crosstool --cpu=arm64-v8a --host_crosstool_top=@bazel_tools//tools/cpp:toolchain --cxxopt="-std=c++11"
