Might as well spend the time to answer my own question:

Some Googling indicates that __ANDROID__ is baked into the NDK
toolchain, so it's definitely what one would use to wrap
Android-specific code.

"__ANDROID__ shall always be defined by the toolchain, without a need
for special flags though, so please rely on that instead in your
code." - David Turner, Android NDK Lead, 2010.
