[$] The current state of Linux architecture support

There have been several recent announcements about Linux distributions changingthe list of architectures they support, or adjusting how they build binaries forsome versions of those architectures.Ubuntu introduced architecture variants, Fedoraconsidered dropping support for i686 butreversed course after some pushback, and Debian developershave discussed raising its architecture baseline for the upcomingDebian 14("forky").Linux supports a large number of architectures, and it's not alwaysclear where or by whom they are used. With increasing concerns about diminishing support for legacyarchitectures, it's a good time to look at the overall state of architecturesupport on Linux.
