Yes, building against a clean tree. I have tried this on 4 different 
build hosts:

1) Centos 5.0 i386: gcc4.1.2 - FAIL
2) Debian Etch i386: gcc4.1.2 - FAIL
3) Ubuntu 7.04 i386: gcc4.1.2 - FAIL
4) Ubuntu 8.10 i386: gcc4.3.2 - PASS

For all of the failures, the appropriate part of the config.log file is 
as follows:

configure:2567: checking for suffix of object files
configure:2588: 
/tmp/br/powerpc/toolchain_build_powerpc/gcc-4.3.2-initial/./gcc/xgcc

See `config.log' for more details.

Unfortunately, the Ubuntu 8.10 machine I used last night to test on is 
not available to me at the moment, however, I am currently getting a new 
VM set up with Ubuntu 8.10 on it, on which I will install gcc4.1.2 to 
see if that is in fact the culprit, but I am not really convinced.

Any thoughts would be appreciated
