Add Android NDK build files.
This adds a Android.mk build that builds a Ceres static library
suitable for embetting in larger Android applications. This is
useful when needing to build Ceres without GPL'd components, since
the standalone toolchain (needed for the CMake Android build) does
not work with STLPort.
