utils: indicate that the old driver is in effect

compnerd · compnerd · commit 4daab4a904f6 · 2025-05-11T17:04:17.000-07:00
We currently cannot boostrap the toolchain with an early swift-driver.
Mark that we are using the old driver. Once the new experimental SDK is
packaged, we should be able to start building the early swift-driver
with static linking to use the bootstrapped driver.
