Link failures of ArcticFox on PPC

Hi!

now that my iBook G4 is roughly working (still some issues... but enough 
to login also remotely and build and compile) I started to compile ArcticFox

I have 1.4GB is ram, which is tight, but enough on intel or linux, with 
enough swap. First attempt failed to link for out of swap, I added swap 
and got further.

It builds for... almost 10 hours but then fails:

do you have an idea where these symbols come from? what's wrong? On 
NetBSD amd64 all builds fine, on Linux PPC again builds so I wonder if 
something is strange in NetBSD/PPC here? a bell rings? I don't know 
these Stub and Sentinel symbols.
