#67 configure script needs regenerating for ARM64/Apple Silicon

[Dominyk Tiller]

The current shipped configure script falls apart when it encounters Apple Silicon, immediately aborting the build:

checking build system type... configure: error: /bin/sh ./config.sub -apple-darwin20.4.0 failed

Running autoreconf -fvi regenerates the configure script successfully and allows building an arm64 binary on Apple Silicon as desired without any further modifications, but it'd be nice if upstream could possibly do that so downstream package managers don't have to do so themselves.
