FS#777 - scripts/ipkg-make-index.sh in SDK failed to generate package index
User who did this - Jo-Philipp Wich (jow-)

----------
Another, more convenient way is simply running "make package/index" this will invoke "ipkg-make-index.sh" and take care of the PATH and other environment variables automatically.
