- 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.

If the user hasn't set EXTERNAL_TOOLCHAIN, but CODEBENCH_PATH is set, then we
automatically set both EXTERNAL_TOOLCHAIN and EXTERNAL_TARGET_SYS based on the
installed toolchains in CODEBENCH_PATH/../toolchains.
This adds a new variable, rather than allowing EXTERNAL_TOOLCHAIN to point to
CodeBench instead of the actual toolchain path, to keep the clean separation
between the generic toolchain logic and that which is specific to our
toolchains, and also avoids overloading the variable's meaning.
