I fear using environment variables for this purpose is a bad idea, which is
why the GCC developers always rejected requests to add such a feature: if
the compilation environment is affected by env vars in this way, it becomes
impossible to see from the command line which commands are executed and it
becomes very hard to figure out what is actually being run.
