[OE-core] BB_SIGNATURE_HANDLER = "basichash" unusable strict?

Today I've started build from scratch and dediced to give basichash a try (as it is supposed to become default IIRC):

So after cleaning tmpdir, sstate cache, pseudo I've started clean build..

1) bitbake -k gcc-cross | tee -a log.${MACHINE}; 
2) bitbake -k virtual/kernel | tee -a log.${MACHINE}; 
3) bitbake -k core-image-core | tee -a log.${MACHINE}; 
4) bitbake -k shr-lite-image  | tee -a log.${MACHINE}; 

But then I've noticed that after successfull build of gcc-cross in step 1 it started another gcc-* build in step 2..

Ah.. yes I did 2 small patches to libxml2 and openssl between step 1 and step2:
http://patchwork.openembedded.org/patch/14521/
http://patchwork.openembedded.org/patch/14519/

But do we want to rebuild everything after every change small like this?
Or is it configuration issue or just bug in sstate implementation?

Btw libxml2 isn't first difference.. I can dig more..

I have few extra patches in my branch so for this particular test case you also need ie
http://patchwork.openembedded.org/patch/13699/

But it shouldn't be hard to find similar issue for any other dependency tree (ie with git-native instead of subversion-native).
