I don't think we should do this (nor the original uuid compat hack
above). We don't want to set an expectation that configure arguments
are considered "stable" interface to QEMU requiring back compat.
This will constrain our future build system work as we move to
introduce meson initially and then gradually elminate more & more
of configure until it can be deleted entirely.

Certainly we should document configure arg removals in the release
notes, but we don't need to go beyond that IMHO.

Daniel
