build failure on powerpc with current -git

["Chris Friesen" <cfriesen@nortel.com>]

The current -git fails to build on 64-bit powerpc (failure log below) . 
  Initially I tried using my older toolchain, when I first saw the 
problem I built a new toolchain with crosstool (gcc 4.1.2 and binutils 
2.16.1) and tried again but got the same problem.

2.6.27 doesn't show this problem.

Any ideas what's going on and how I can fix it?

Thanks,

Chris
