I find that -c clean does not work very well, afterward the package gets
recompiled but instead of the actual package packages being rebuilt, an
earlier version of the packages gets pulled out of sstate into the
image. I definitely saw this behaviour with Yocto kernels, but I think
happens with other packages as well; I always do -c cleansstate now to
avoid this.
