I think the problem is in staging_populate_sysroot_dir(). It's
confusing target and native package_archs since in the case we see this
its x86_64 where the target and build archs match.

Not entirely sure how we'll fix this but that is where I think the
problem is.

Not sure why we're suddenly seeing it now and whether the patches
somehow trigger it or not...

Cheers,
