This is a known caveat of using uninative. The version of libc in
uninative needs to be greater than or equal to the version on the host
system. We tend to keep the version of uninative up to date and this
therefore works.

We did run into version issues and I believe master is better at
detecting the version mismatches now and recovering from it by
disabling uninative.

I'd be very happy if someone can come up with a better way of making it
work (with the same performance) but the current solution works as well
as we can make it right now and you can choose if you use it or not.

Cheers,

Richard
