The following tests are done, all passed:

- fetch source for world with DISTRO = "poky-bleeding", all passed except
  two broken recpies whose SRC_URI are obsolate, two bugs 623,624 are
  filed for this.
- bitbake poky-image-sdk for qemux86 with empty DL_DIR
- bitbake poky-image-sdk for qemuppc with empty DL_DIR
- bitbake poky-image-sdk for qemumips with empty DL_DIR

BTW, Richard, could you take a look and provide comments on this? I'd like to
revise them accordingly and prepare another submit for code check in.
