It seems that you had re-run the oe-init-build-env since when no BB_STAMPS_DIR
it would print errors., I think that the problem is  the "bitbake -S" didn't
work well since it has bugs, I have updated the related code a little, and it
would tell what's wrong:

         # FIXME
         # The "bitbake -S" may fail, not fatal error, the stamps will still
         # be generated, this might be a bug of "bitbake -S".
         try:
             bb.process.run(cmdline)
         except Exception as exc:
             print(exc)

I have pushed it to git repo, it would be great if you can help me to test it,
and I will invite you beer when you come to Beijing:-)
