commit d42869c1e6fbb5caf87428662825840b2e70a19d
Date: Thu, 29 Oct 2020 20:54:59 +0530
Subject: [android] Move to the NDK's unified sysroot

Since the NDK is removing the platforms/ and sysroot/ directories in the next
release, switch to the unified sysroot in toolchains/llvm/ and take advantage
of a bunch of simplification that's now possible.
