[Buildroot] Incorrect sysroot?

The external toolchain was built using Atmel's AVR32 buildroot which can
be downloaded from http://www.atmel.no/buildroot/buildroot-src.html

It compiles runnable c code, and compiles c++ code which I cannot run on
the target because the target's image does not include libstdc++

The (ICnova) buildroot in which I am attempting using the Atmel
toolchain is intended to produce an image containing libstdc++. This
buildroot was sourced from the target board's manufacturer. For some
reason, it will not produce a viable cross-toolchain. That is why I am
attempting to use the Atmel toolchain as an external toolchain.
