lets split this out a little bit. Code additions should not be intermixed with additions to the build system and especially configure options.

I rather not have a top-level Android.mk. It should be enough to provide an android/Android.mk.

If we keep using prefix btd_ for certain set of functions, then it might be better if the daemon is build as android/bluetoothd or android/btd.

I do not think we need to include hcid.h here. If we for some reason still do, then please try to cleanup that first.

Make this static volatile bool __terminated = false instead. Remember that you are actually using signals here and not signalfd.

Do we need this option at all. I think we should always run in foreground and the system manager need to make sure we are spawned.

I prefer if we start using return EXIT_SUCCESS and in error case EXIT_FAILURE.

This needs to be a separate patch. And it should just say --enable-android.

In addition it needs to be added to bootstrap-configure and distcheck handling.
