Android NDK , C++11 and the wrong stdlib

Trying to compile a C++11 library using the android ndk(android-ndk-r10d) and a standalone toolchain results in many errors along the lines of

 error: no member named 'to_string' in namespace 'std'

This seems to be the same across using GCC or clang. The toolchain is generated with :

 ./make-standalone-toolchain.sh  --platform=android-19 --install-dir=/home/ian/android_standalone/ --ndk-dir=/home/ian/androidndk/android-ndk-r10d/ --arch=arm --system=linux-x86_64  --stl=gnustl

And compilation is via:

cmake -DCMAKE_TOOLCHAIN_FILE=../android.toolchain.cmake -DCMAKE_BUILD_TYPE=Release -DANDROID_ABI="armeabi-v7a with NEON" -DANDROID_STANDALONE_TOOLCHAIN=/home/ian/android_standalone/   ../

Almost all of the suggestions for fixing this involve ensuring you are passing -stdlib=c++11 to the compiler. However that is not a problem here:

There seems to be something generically wrong with setting up an android toolchain that supports c++11.
