Absolutely, it's a real bug that should be fixed. What is counterproductive is 
that this rare and hard to replicate build modus is now a must-have test for 
linux-next inclusion.

I already cross-build to 20+ weird, rarely used architectures, slowing down the 
linux-next merge integration test immensely and wasting quite a bit of 
electricity. linux-next making it even harder to test for is a step backwards.

Thanks,
