Segregate the cpu name for aarch64-linux and aarch64-qnx

[andi4191]

We need to use separate cpu name for aarch64-linux and aarch64-qnx in order to prevent the libraries from clubbing with each other.

The project already use toolchain of bazel to build for different target machine.

	#### aarch64-linux
	##### Applicable to DRIVE AGX Platforms flashed with the Linux PDK and Jetson AGX Platforms
	> In order to use this toolchain you must and have built a container that supports aarch64-linux (Dockerfiles will have names that contain `aarch64-linux` or `both`)
	To cross-compile targets for aarch64-linux append the following flag to your build command: `--config=D5L-toolchain`
	- e.g. `dazel build //plugins/dali/TensorRTInferOp:libtensorrtinferop.so --config=D5L-toolchain`
	You will find the associated binaries in `//bazel-out/aarch64-fastbuild/plugins/dali/TensorRTInferOp/libtensorrtinferop.so`
	> Note: `D5L-toolchain` is aliased to `L4T-toolchain` for Jetson users' convenience
	#### aarch64-qnx
	##### Applicable to DRIVE AGX Platforms flashed with the QNX PDK
	> In order to use this toolchain you must obtain the QNX Toolchain and have built a container that supports QNX (Dockerfiles will have names that contain `aarch64-qnx` or `both`)
	To cross-compile targets for aarch64-qnx append the following flag to your build command: `--config=D5Q-toolchain`
	- e.g. `dazel build //plugins/dali/TensorRTInferOp:libtensorrtinferop.so --config=D5Q-toolchain`
	You will find the associated binaries in `//bazel-out/aarch64-fastbuild/plugins/dali/TensorRTInferOp/libtensorrtinferop.so`
	#### Building for older PDKs
	By default `--config=[D5L/D5Q/L4T]-toolchain` will target the latest supported version. Since versions might use slightly different dependencies, to build using an older build container
	you will also need to specify the exact PDK version you are targeting.

I think this can be closed. @andi4191

As mentioned by Zhensheng Lee, this can be closed. And this topic is also no longer relevant
