(incomplete) Add files required to compile for Android via Pico driver.

Don't get your hopes up just yet: this code does compile, but it doesn't fully link yet. If you like to test this, install the Android SDK and NDK, set the usual environment variables, then change into the "Android" direktory and run "mk". It will currently fail at the linker stage.
