Subject: [PATCH] [3.13] gh-145616: Detect Android sysconfig ABI correctly on
 32-bit ARM Android on 64-bit ARM kernel (GH-145617)

When Python is running on 32-bit ARM Android on a 64-bit ARM kernel, `os.uname().machine` is `armv8l`. Such devices run the same userspace code as `armv7l` devices, so apply the same `armeabi_v7a` Android ABI to them, which works.
(cherry picked from commit 3a2b81e919103c0be3bc60a47aaa74d34fea6e9e)
