configure should pick up the newly built gcc here, not the one that is 
already installed (libstdc++ should be compiled by the just bootstrapped 
compiler). I guess at the point where configure is invoked, some flag 
should be passed, but I don't know anything about the libstdc++ build 
machinery, to be honest.
