The current bionic header gives us a clearer picture: https://android.googlesource.com/platform/bionic/+/master/libc/include/math.h#240

So yes, most of these were missing until somewhat recently. `libandroid_support` provides these things though (if it's missing any, that's still the right place to fix this).

We've also debated just defaulting to using a static libm for Android since all that stuff can be safely statically linked across platform versions, so there's really no reason to not always use the latest version.
