Local reference table overflow in JNI code fixed.

* fix formatting
* honor Windows-style paths
* suppress warnings inside try_compile
* correct caching of toolchain variables

To speed up rebuilds, define the NDK_CCACHE environment or CMake variable
to the path to your ccache binary. When declared, the android.cmake.toolchain
automatically uses CCache when compiling any C/C++ source file. For example:

export NDK_CCACHE=ccache
