We can already do that with BB_STAMP_POLICY, the problem present is that 
it will generate packages with the same PV and PR, so it won't show up 
as upgrade, so users get a broken installation after the package manager 
upgrades the kernel, but not the modules since PV and PR didn't change 
for those.
