Subject: [PATCH] Pass ANDROID_ABI and ANDROID_PLATFORM environment variables

Uses environment variables as passed by cargo-ndk version 4.0 and later,
and passes them as defines to cmake.
Note the environment variable names as currently documented on
<https://crates.io/crates/cargo-ndk> are outdated, the docs have been
fixed later in <https://github.com/bbqsrc/cargo-ndk/commit/1bee04b305>.

fixes #226
