tbh I'd vote for runtime detection, we could simply add a debugfs file on
the internal tree which exposes dev_priv->is_simulator. Or heck merge that
part upstream even.

Imo that's better since iirc QA is using a central build server and
distributes binaries to test machines. Ofc they need to build different
sources already, but different options is a bit more messy than just
changing the git remote ...
