For any platform(s) you support, please reply with any relevant details that should be added to the relevant tables below. Once I have these details I will loop back with the proposed update to PEP 11 and make sure everyone is still on board with the proposal.
A few remarks:
autoconf, GCC, and Debian call it "Target Triplet". Clang and Rust use "Target Triple". Should we stick with the clang name or use the GCC name?
Target triplets are machine-vendor-os. They come in short, normalized form and in long, extended form. The normalized form often omits the vendor field. Your document has both long and short forms. "wasm32-unknown-emscripten" is extended form for "wasm32-emscripten", while "x86_64-windows-msvc" is the short form of "x86_64-pc-windows-msvc". I recommend to stick to one convention.
Whatever you all tell me. 😉 I did the best I could on what the Rust tiers listed and what I know.
By the way config.guess script and gcc can dump the current triplet. The config.sub script can be used to normalize and validate a triplet (does not work for MSVC). The output of config.guess is more specific than the gcc machine info. Here is a dump from my RPi:
$ ./config.guess armv7l-unknown-linux-gnueabihf $ gcc -dumpmachine arm-linux-gnueabih $ ./config.sub arm-linux-gnueabihf arm-unknown-linux-gnueabihf

It's a bit premature to add wasm32-wasi. Python doesn't even compile on WASI yet.
