This test is meant to test the most basic level of exception support
even if you are not using a regular C++ STL. No <stdexcept> required.

Normally, the only thing needed is adding -fexceptions to your LOCAL_CFLAGS
and that's it. Alternatively, use it in APP_CFLAGS to add the flag to all your
modules at the same time.

This is really a way to check that the C++ compiler properly links against
libsupc++.a without any kind of conflict, and that the try / throw / catch
features do really work.
