These are the correct locations.

And this would be wrong.

libstdc++ and its headers are GCC/g++ internal libraries (comparable to 
libgcc) and are part of a cross-gcc. I.e. cross-g++ needs to use its its 
libraries/headers and not those inside of a sysroot.

What confuses people, is Linux vendors relocating libstdc++ and its 
headers into /usr for native compilers.
