AIX architecture problems

[david at thekramers.net (David Kramer)]

Background: AIX 5.2 box.  My mission is to port my company's application
from AIX's native xlC compiler to the GNU toolchain.  I bootstraped gcc
3.4.0 from a gcc 3.3.3 (build for AIX5.1) I downloaded.  I built gcc with
an architecture of "powerpc-ibm-aix5.2.0.0".  I'm still using a binutils
built by someone else.  I can tell you this:

/opt/local/bin/ld: supported targets: aixcoff-rs6000 aix5coff64-rs6000 
srec symbolsrec tekhex binary ihex
/opt/local/bin/ld: supported emulations: aix5ppc
/opt/local/bin/ld: emulation specific options:
  no emulation specific options.

/opt/local/bin/ld -v
GNU ld version 2.14 20030612

I've got all the code compiled using g++ to .o files after some pretty
significant changes, but linking produces output I don't understand.  
Here's a shortened version of the output:

So does this mean I need to rebuild binutils, or is there some command 
line option I'm missing?

Thanks in advance.  I did STFW, but most of the references I found were
problems with 32/64 bit incompatibilities, which I don't think is the
problem here.
