Installing all arm-gcc-bin results in failure to link newer ones (at least for M1 Mac).

I'd be okay with keg only /opt/homebrew/opt installations for all of these if that is easier or all but the latest version, which could be installed if that makes it simpler.

See the console log below.

By the way, thanks for this project, it's really useful!

I agree -- I'm happy to review a PR if you have time.
