I also have big problems that libtool tries to  use  /usr/lib/libstdc++ 
instead of the compiler one, when I compile several projects.

IMO libtool should always ignore libstdc++, but this is another issue. 

I solve the problem by patching libtool after configuration.  I change 
sys_lib_dlsearch_path_spec  and sys_lib_search_path_spec such that 
${GCCDIR}/lib  is the first entry followed by  the default values. This 
solves the problem most of the time, but I still hate that libtool does not 
ignore libstdc++ in such projects.
