meta-toolchain-arago already handles all the above, including feeds and 
package-management. It may not be very minimal, sure, but at least it contains 
the minimal toolchain to be useful. I'd rather look into shrinking existing 
meta-toolchain-arago, especially since there's a larger version called 
meta-toolchain-arago-tisdk...
