Summary
Installing scikit-learn on aarch64 via pip using command "pip3 install scikit-learn" tries to build wheel from source code

Problem description
scikit-learn don't have wheel for aarch64 on PyPI repository. So, while installing scikit-learn via pip on aarch64, pip builds wheel for same resulting in it takes more time to install scikit-learn. Making wheel available for aarch64 will benefit aarch64 users by minimizing scikit-learn installation time.

Expected Output
Pip should be able to download scikit-learn wheel from PyPI repository rather than building it from source code.

@scikit-learn-team, please let me know if I can help you building wheel/uploading to PyPI repository. I am curious to make scikit-learn wheel available for aarch64. It will be a great opportunity for me to work with you.
