That config.log is useless, you'd need to look in the libstdc++-v3/config.log But I'm pretty sure the problem is you're missing the locale data files, which is nothing to do with gcc or libstdc++. Why don't you try Axel's suggestion of using strace to see what files it tries to open, then you'll know what you're missing.
