We have unfortunally no way of knowing if this is correct as the github builds are not buck2 based, but we have tried to dry-code what we think will work for you.

@digantdesai can you please verify if this change fixes the internal issues?

[zingo]

@shoumikhin @digantdesai as we soon are moving out of the local working window :) feel free to just merge this directly when you approve it and not wait for me, as I assume you want to fix this faster them my response time might be, Ill try to keep an eye on it anyway if you don't but it might take a bit of time :)

Fails are unrelated

Thanks @zingo for the bold attempt, while flying blind. Let me test it.
I think we should enable buck2 AoT unit tests (at least for TOSA) in OSS. Let me do it next week.

A better fix for this was merged #14031
