STATUS: FAILED
BUILD: master:4da406cd50cf02a63ed76810a670aba1eb561c79
ENVIRONMENT: Ubuntu 12.04 x86-64
STEPS TO REPRODUCE: Check if the script could clean the obsolete sstate cache files

1. Download poky source and prepare the build environment. 
2. Follow the wiki steps to setup a sstate cache on local machine, 
https://wiki.yoctoproject.org/wiki/Enable_sstate_cache 
3. Run "bitbake core-image-minimal" to build a image. 
4. Set MACHINE to another architecture. Run "bitbake core-image-minimal" to build a image. 
5. Run script ../scripts/sstate-cache-management.sh --cache-dir=sstate-cache --remove-duplicated and check the ouput.


EXPECTED OUTCOME: The obsolete sstate cache files should be removed.

ACTUAL OUTCOME: After building core-image-minimal for qemux86-64 and qemuarm:

[cornel@NODE3 build]$ ../scripts/sstate-cache-management.sh --cache-dir=sstate-cache --remove-duplicated
