what you want to do just wont work regardless of the issue you raise below ... 
gcc 3.3 and gcc 3.4 have incompatible ABI's so you cannot mix things built 
with the two compilers as you'll just end up with some things using 
libstdc++.so.5 while others use libstdc++.so.6

this is a feature of libtool and will always cause you problems when you try 
to mix compilers that use gcc libtool files

the linker scripts (.la) encode the full path to the actual linker script ... 
so when you build a C++ app, the .la file will encode the full path to the 
libstdc++.la file from the gcc compiler that was used to build it
