It does make sense, but the toolchain is then stripped down in such fashion that 
it's rather useless. Still, would you mind commenting on the patch sent to the

Yes, this does make sense. But then, this also means the toolchain becomes 
useless for general use.

Urgh, this was not really helpful answer.

Uh, OK.
