The VM comes with the *SDK*. AFAIU, Android Apps can't be standalone
native executable. It must have a Java (Dalvik) laucher which calls the
native part as JNI.

Please note file docs/STANDALONE-TOOLCHAIN.html. It says that without
installing the toolchain in different location, RTTI, STL and exceptions
can't be used.
