Hi Iain, thanks for looking into this.
The above patch worked for me when I tried to re-run it in my previously failed
build dir.  I didn't try to resume the bootstrap from there.  

At the same time I also kicked off a --disable-multilib build. 
Also running on dual 533MHz G4, -j2 here, so results in half-a-day, though I
might be slow responding over the weekend.  :)
