Of course this will need to go upstream as well.

Yes, I'm planning to send it to upstream (9.x) as well file backport to 8.x request release after flag day, or at least when plan is officially announced.
What do you and @jhibbits think about it?

The change itself LGTM.

From a previous discussion these days, it seems the consensus was to propose it to LLVM upstream some time after FreeBSD itself commits the ELFv2 changes.
As this changes a previous default, I'm not sure if this change is eligible for backporting, but LLVM community knows better about it.
