Rationale: our arg refurbishment is normally only turned on when called via the `make` wrapper, for compatibility reasons. However, there are numberous places we'd like this to be turned on elsewhere, like software that builds via `python setup.py` where bad flags from the system python can be pulled in. This helper appends 'O' to CCCFG, which enables refurbishment for all calls of the compiler shims.
