1/2 an answer to the sstate question; it looks like something has changed the
[md5] hash on the state files.  I ran bitbake with strace to see what files it
was looking at, for example, it tried to look at
   sstate-libxau-native-i686-linux-1.0.6-r0-i686-2-c96b705204df4a0b4b85a9629d15fe53_populate-sysroot.tgz
when the old sstate held
   sstate-libxau-native-i686-linux-1.0.6-r0-i686-2-cb04fd60d897b3222c3c046e571117ff_populate-sysroot.tgz

What controls this hash and why did it change for every package?
