Comment:

 mingwandroid: Is there a way to avoid downloading all the dependencies
 every time we build the cross-compiler? Can I somehow point crosstools-ng
 to already downloaded sources and convince it to use those instead?
 Ideally, there should be no need for a network connection at all in the
 build phase (after fetching all the sources + installing the necessary
 packages).
