Hi Sumanth,

Thanks for the new version.

This looks better, at least for the dnf install errors. Yet we still
have errors when reusing sstate-cache, as recipes generating pkgconfig
should be rebuilt, but their signatures did not change:

https://autobuilder.yoctoproject.org/valkyrie/#/builders/4/builds/4377

I made some horrible hack in my branch to change the PR of many
recipes, and the build now succeeds. I only tested one configuration,
but we can expect similar results on the other ones.

https://autobuilder.yoctoproject.org/valkyrie/#/builders/4/builds/4386

So, depending on how you address Ross comment, you might need to make
sure recipes signature is going to change.

We also had some selftest errors: I will investigate a bit further and
come back to you.

Thanks,
Mathieu
