From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Check for __arm64__, not just __arm__
On at least one 64-bit ARM processor I've tested (Apple Silicon on macOS),
__arm__ isn't defined but __arm64__ is. As a result, some of the
ARM-specific macros are missing and calls to them fail.
