This is because subarch.include invokes `uname -m` which on MacOS hosts evaluates to `arm64` but on Linux hosts evaluates to `aarch64`, This allows us to build ARCH=arm64 natively on MacOS (as in ARCH need not be specified on an aarch64-based system). Utilize a negative lookahead regular expression to avoid matching arm64. Add a separate expression to support for armv.* as per error reported by Nicolas Schier [1].
