IME, it is much better when any override mechanism make use of environment
variables.  These are very easy to set per-build, per-user and system-wide,
unlike system-wide files and even per-project files.

It would be enough for the environment variables, when present, set the name
of the override files, and default to local config.{sub,guess}.override or
whatever when the variables are not set.
