r=oli-obk [AVR] Replace broken 'avr-unknown-unknown' target with 'avr-unknown-gnu-atmega328' target The `avr-unknown-unknown` target has never worked correctly, always trying to invoke the host linker and failing. It aimed to be a mirror of AVR-GCC's default handling of the `avr-unknown-unknown' triple (assume bare minimum chip features, silently skip linking runtime libraries, etc). This behaviour is broken-by-default as it will cause a miscompiled executable when flashed. This patch improves the AVR builtin target specifications to instead expose only a 'avr-unknown-gnu-atmega328' target. This target system is `gnu`, as it uses the AVR-GCC frontend along with avr-binutils. The target triple ABI is 'atmega328'. In the future, it should be possible to replace the dependency on AVR-GCC and binutils by using the in-progress AVR LLD and compiler-rt support. Perhaps at that point it would make sense to add an 'avr-unknown-unknown-atmega328' target as a better default when implemented. There is no current intention to add in-tree AVR target specifications for other AVR microcontrollers - this one can serve as a reference implementation for other devices via `rustc --print target-spec-json avr-unknown-gnu-atmega328p`. There should be no users of the existing 'avr-unknown-unknown' Rust target as a custom target specification JSON has always been recommended, and the avr-unknown-unknown target could never pass the linking step anyway.

2020-08-13Auto merge of #75431 - ehuss:platform-support, r=Mark-Simulacrumbors-5/+234
Move platform support to the rustc book. This moves the [Platform Support](https://forge.rust-lang.org/release/platform-support.html) page from the forge to the rustc book. There are several reasons for doing this: * The forge is not really oriented towards end-users (it mostly contains infrastructure, governance and policy, internal team pages, etc.). This platform support page is useful to user to know which targets are supported. * This page can now be updated in-sync with any PRs that add or remove a target, or change its status. * This is now automatically checked on CI to verify the list does not get out of sync. Currently it only checks the presence/absence of an entry, but more sophisticated checks could be added in the future. I'm not 100% certain this is the best location, but I think it fits. I'd like to see the rustc guide continue to grow, including things like linking information and more platform-specific details.

2020-08-11Platform Support page updates.Eric Huss-193/+198
A few updates: - Some minor wording and formatting changes. - Remove the `cargo` column. - Explain the columns up-front. - Add no-wrap on the target-triple, which looks better to me. - Minor mention on how to install support for a built-in target via rustup.
