reported by @masahi

After updating to the latest main, I'm seeing too many LOG(INFO) from src/target/compilation_config.cc . Below is the log emitted when compiling a single dense op.

[15:51:23] /home/masa/projects/dev/tvm/src/target/compilation_config.cc:87: Using the unique primitive target Target(kind='llvm', keys={'cpu'}, attrs={"link-params': (bool)0}) of device type 1 for the host target
