There is not much info in config.log
The last part in config.log is

I have not specified any options to configure.
just ./configure and gmake

libstdc++v3 is being compiled with  (this is from config.log )

/mnt/gcc-4.3.2/libstdc++-v3/configure --cache-file=./config.cache
--enable-multilib --enable-languages=c,c++,fortran,java,objc
--program-transfor
m-name=s,y,y, --with-target-subdir=powerpc-ibm-aix5.3.0.0
--build=powerpc-ibm-aix5.3.0.0 --host=powerpc-ibm-aix5.3.0.0
--target=powerpc-ibm-aix5.3.0.0 --srcd
ir=../../gcc-4.3.2/libstdc++-v3

Any ideas why it might be failing. config.cache remains empty and
every time i do this it takes lot of time as it tries to do all this
again. Looks like this is 3 rd stage in compilation.
cat stage_* show stage3 for all three files. Is there any workaround
to skip this. I do not really care what the output gcc will be capable
off. it should just be able to compile itself. Its more of an i/o test
in my setup.
I can provide more information if required.
