Bug 964

I'm using the latest git master commit e5a40cd6f8c6a8c3d40cbaf29bffe5e201056dad and found the issue:

After "bitbake file-native", we can see the list of the populated files in
tmp/sstate-control/manifest-i686-file-native.populate-sysroot
e.g., a populated file is
tmp/sysroots/i686-linux/usr/lib/libmagic.so

Later, after doing "bitbake -c cleanall file-native", I found the file
tmp/sysroots/i686-linux/usr/lib/libmagic.so
was not really removed!

This looks be caused by a recent commit that breaks an assumption of the order between SSTATETASKS and SSTATETASKNAMES.

    sstate: use only unique set of SSTATETASK

    * otherwise strange error like this:
      ERROR: Logfile of failure stored in: /OE/shr-core/tmp/work/armv7a-oe-linux-gnueabi/libtool-cross-2.4-r1/temp/log.do_package_write_ipk.25551
      Log data follows:
      | ERROR: Package already staged (/OE/shr-core/tmp/sstate-control/manifest-nokia900-libtool-cross.deploy-ipk)?!
      | ERROR: Function 'sstate_task_postfunc' failed
      NOTE: package libtool-cross-2.4-r1: task do_package_write_ipk: Failed
      ERROR: Task 11 (/OE/shr-core/openembedded-core/meta/recipes-devtools/libtool/libtool-cross_2.4.bb, do_package_write_ipk) failed with exit code '1'

      is shown in this case with package_ipk twice in INHERIT

    * Thanks to Richard for fix
