- If the user set EXTERNAL_TOOLCHAIN to the top of the CodeBench install rather than the actual toolchain path, we correct it - If the user set EXTERNAL_TOOLCHAIN to the path to a new CodeBench, where the toolchains are installed elsewhere, set CODEBENCH_PATH instead, so we correctly and automatically set EXTERNAL_TOOLCHAIN When these fixups are performed, warnings are displayed, indicating the correct values for the variables, so the user can set them that way if we they want to silence the warnings.
