Android: Removed custom toolchain file
This commit drops the previous custom CMake toolchain file for Android in favor of CMake's new built-in toolchain for this (CMake >3.7.2). This makes building SFML for Android a lot simpler and more straight forward, working almost as smooth as other platforms. To configure your build directory, all you have to do is defining just a few variables the first time you invoke CMake. **Required Variables** * `CMAKE_SYSTEM_NAME` must be `Android`, so CMake knows we actually want to cross-compile. * `CMAKE_ANDROID_NDK` must point to the NDK's installation directory, e.g. `/usr/android/ndk` or `c:/android/ndk`. **Recommended Variables** * `CMAKE_ANDROID_STL_TYPE` defines the STL implementation to be used. You should use `c++_shared`, although others might work. **Optional Variables** * `CMAKE_SYSTEM_VERSION` can be set to pick a specific SDK version other than the latest. * `CMAKE_ANDROID_ARCH_ABI` defines the target architecture and ABI, for example `armeabi` or `armeabi-v7a`. Based on your system, you might want to enforce a specific generator to prevent issues, e.g. using `MinGW Makefiles`.
