The real include directory is in ${CT_PREFIX_DIR}/${CT_TARGET}/sysroot . The one
you are poiting at is used internally by gcc to find (precompiled?) C++ headers.

You will also notice that there is a ${CT_PREFIX_DIR}/${CT_TARGET}/lib directory
that contains some gcc libraries. They do really belong to the sysroot as well,
but gcc is dumb enough not to install them at the correct place (I thought I fixed
that in crosstool-NG 1.0.0).
