Thanks! That is exactly the information I was looking for.

Understood, makes a lot of sense.

I am (I think) almost there, I expect to be able to succesfully build
hello on my ppc machine soon (it's a slow machine, so iterations take
time). I do not feel like changing to core-updates now (though I would
have been better had I worked there since the beggining). Once I have
bootstrapped, I will review the changes and rebase the "core" ones to
core-updates. I should be there before two weeks' time.

Thanks!
