		// TODO(jiyong): remove below case. This is to work around build errors happening
		// on branches with reduced manifest like aosp_kernel-build-tools.
		// In the branch, a build error occurs as follows.
		// 1. aosp_kernel-build-tools is a reduced manifest branch. It doesn't have some git
		// projects like external/bouncycastle
		// 2. `boot_signer` is `required` by modules like `build_image` which is explicitly list as
		// the top-level build goal (in the shell file that invokes Soong).
		// 3. `boot_signer` depends on `bouncycastle-unbundled` which is in the missing git project.
		// 4. aosp_kernel-build-tools invokes soong with `--skip-make`. Therefore, the absence of
		// ALLOW_MISSING_DEPENDENCIES didn't cause a problem.
		// 5. Now, since Soong understands `required` deps, it tries to build `boot_signer` and the
		// absence of external/bouncycastle fails the build.
		//
		// Unfortunately, there's no way for Soong to correctly determine if it's running in a
		// reduced manifest branch. Instead, here, we use the absence of DeviceArch or DeviceName as
		// a strong signal, because that's very common across reduced manifest branches.
