<h3 dir="auto">Describe the issue:</h3>
<p dir="auto">Release notes document MD5 checksums for universal2 wheels. However, I can't seem to find one.</p>
<p dir="auto">Any attempt to <code class="notranslate">python3 -m pip install numpy  --target foo --platform=universal2</code> results in building from source (asks to add <code class="notranslate">--no-deps</code>), which subsequently fails.</p>
<p dir="auto">What would be the best way to install universal2 (e.g. arm64+x86_64) distribution of numpy?</p>

<h2 dir="auto">Feature</h2>
<p dir="auto">The binary wheels for macOS on PyPI are currently for x86_64. Please also provide a universal2 wheel (x86_64 and arm64) for use with the (currently experimental) universal2 Python 3.9.1 installer on Python.org.</p>
