I have a 64bit Linux system and I need to build boost for 32bit in order 
to link to this library I have to use.  Trouble is that I keep getting 
this error when I try to link to any boost library:

nroberts_at_Adad:~$ g++ test.cpp -m32 -L/home/nroberts/boost-x86/lib 
-lboost_thread-gcc44-mt
/home/nroberts/boost-x86/lib/libboost_thread-gcc44-mt.so: undefined 
reference to `__sync_fetch_and_add_4'
collect2: ld returned 1 exit status

test.cpp just contains an empty main().

I've tried google and arrived at various places:

http://old.nabble.com/compiling-32-bit-boost-libraries-on-a-64-bit-system--%28gcc,-Linux%29-td22087063.html

Among others.  I'm trying to build version 1.38.

Here's my last attempt at supplying bjam with the correct parameters:

bjam architecture=x86 address-model=32 toolset=gcc instruction-set=i686 
stage

It's funny though, even at the link in the reply held at nabble.com the 
documentation doesn't seem to have anything on any of these parameters. 
  They don't appear in the bjam --help output either.  So I seem to be 
kind of screwed in figuring this out myself.  I'm just trying to guess 
until I get it but I'm out of ideas.  What do I need to do?

Thanks.
