[cfe-dev] can't link with libstdc++

Hey, folks!

HelloWorld is compiled but can't be linked with libstdc++ with clang 3.3.
libstdc++ headers are found and the file is compiled. Though i'm using
`clang++` to link and passed `-Lpath` where `libstdc++.a` is located it
can't find `std`.

I've tried GCC with the same paths and LD_LIBRARY_PATH and it's able to
compile and link.

Clang's compile and link output:

libstdc++.a is on the -L path:

    MBA-Anton:platform-tools asmirnov$ ./adb shell ls -l
/data/data/name.antonsmirnov.android.arduinodroid/sdk/libstdc++-compact-dev#4.8#1/arm-linux-androideabi/lib
    -rwxr-xr-x u0_a122  u0_a122   7707492 2014-01-24 18:36 libstdc++.a
    -rwxr-xr-x u0_a122  u0_a122    674120 2014-01-24 18:36 libsupc++.a

I've also tried to pass `-stdlib=libstdc++` but still getting the same
error. Since i've copied the libs myself i can be wrong in paths or smth
(but GCC works with the same paths). Any thoughts?
