Compile tvm with bazel can't involve llvm

Question

I tried to compile TVM with bazel, but block in src/target/llvm. Here is my TVM bazel BUILD file

cc_library(
name = "llvm_compiler",
srcs = glob([
    "src/target/llvm/*.cc",
]),
hdrs = glob([
    "src/target/llvm/*.h",
    "src/target/*.h",
]),
deps = [
    "//3rdparty/clang+llvm-9.0.0-x86_64-linux-gnu-ubuntu-16.04:llvm",
    ":compiler_hdrs",
    ":runtime_hdrs",
    ":arith_hdrs",
    ":implicit_hdrs",
    ":tir_hdrs",
],
copts = [
    "-DTVM_LLVM_VERSION=90",
    "-O0",
],
# alwayslink = True,
linkstatic = True,
visibility = ["//visibility:public"])

And I add this file into clang+llvm-9.0.0-x86_64-linux-gnu-ubuntu-16.04.tar.gz which download from web

cc_library(
    name = "llvm",
    srcs = glob([

        "-D__STDC_LIMIT_MACROS",
        "-DDMLC_USE_FOPEN64=0",
    ],
    visibility = ["//visibility:public"],
)

When I run this libtvm.so, it complain that:

TVMError: Check failed: bf != nullptr: target.build.llvm is not enabled

So I change llvm_compiler as alwayslink=true, but it complain

OSError: lib/libtvm.so: undefined symbol: _ZTIN4llvm6legacy11PassManagerE

And I tried this thread: Building LLVM with Bazel, with code : https://github.com/dgp1130/llvm-bazel-foolang, but the error reported is same.

Everything works fine on CMake, I don't know what's different with Bazel. And actually, I only hope "TVM_REGISTER_GLOBAL("target.build.llvm")" not delelte by gcc.

Thanks!
