What's the reason around the first bitbake?  I know with pstage you
needed to do that for an empty TMPDIR to populate out everything else,
but sstate shouldn't have that weakness.  It should just be:
$ bitbake virtual/kernel -c menuconfig
$ bitbake virtual/kernel

And get populating from sstate correct.
