PiBox

There are options for managing specific package builds in Buildroot's help:

  <pkg>-source           - Only download the source files for <pkg>
  <pkg>-dirclean         - Remove <pkg> build directory
  <pkg>-reconfigure      - Restart the build from the configure step
  <pkg>-rebuild          - Restart the build from the build step
  <pkg>-reinstall        - Restart the build from the install step

I should add these to the buildroot.mk targets so that rebuilding things like libpibox are easier. However, it's not clear if the -source target will re-download if the archive is already downloaded.
