Auto merge of #33211 - alexcrichton:android-back-in-time, r=nagisa
std: Add compatibility with android-9 The Gecko folks currently use Android API level 9 for their builds, so they're requesting that we move back our minimum supported API level from 18 to 9. Turns out, ABI-wise at least, there's not that many changes we need to take care of. The `ftruncate64` API appeared in android-12 and the `log2` and `log2f` APIs appeared in android-18. We can have a simple shim for `ftruncate64` which falls back on `ftruncate` and the `log2` function can be approximated with just `ln(f) / ln(2)`. This should at least get the standard library building on API level 9, although the tests aren't quite happening there just yet. As we seem to be growing a number of Android compatibility shims, they're now centralized in a common `sys::android` module.
