Merge ~mateus-morais/ubuntu/+source/ivar:fix-ivar-ftbfs into ubuntu/+source/ivar:ubuntu/devel

[Mateus Rodrigues de Morais]

This aims to fix ivar FTBFS on amd64 and arm64 by disabling LTO.

PPA test build: https://launchpad.net/~mateus-morais/+archive/ubuntu/ivar-ftbfs

Hi Mateus,

The change itself looks fine but the tests are failing in the PPA build. Let's look into that before we go further.

[Graham Inggs (ginggs)]

Dan, unless I missed something, the buid-time tests passed on amd64 and arm64.
ivar has never built on armhf, ppc64el and s390x before, so let's not block on that.

I also triggered the autopkgtests in the PPA and they succeeded on amd64 and arm64:
