Error out if requesting Android build without toolchain file

Browse Source 
Passing Android-related variables to the initial CMake call would have
no effect if no (or an empty) value of CMAKE_TOOLCHAIN_FILE was
specified. To alleviate user confusion, yield an error if an Android
build was apparantly requested, but the toolchain file is missing.
