In fact this also overrides the user selection for some of the single platform kernels, for example I don't think DEBUG_LL can be targetted at ICE or semihosted supervisor for ARCH_VERSATILE. This happens because DEBUG_UART_PL01X is automatically enabled by some architectures and this means user decisions made regarding the DEBUG_LL backend will be overriden. Problem is fixed by removing the automatic enabling of this option.
