I.e. this prevents QCOM_Q6V5_WCSS to be compiled builtin when RPMSG_QCOM_GLINK_SMEM is module, as this would give us both stubs and the module. > RPMSG_QCOM_GLINK_SMEM=n should be for the COMPILE_TEST.

For the two first we want it to be possible only compile the specific transport being used and the other being stubbed. As Sricharan's particular platform uses GLINK for communicating with the WCSS it's perfectly fine to run this particular driver with RPMSG_QCOM_SMD=n RPMSG_QCOM_GLINK_SMEM=y/m As such I would recommend that you drop COMPILE_TEST from above.
