Changes: https://github.com/WebAssembly/wasi-sdk/releases/tag/wasi-sdk-34
https://github.com/WebAssembly/wasi-sdk/releases/tag/wasi-sdk-33
- sync CMAKE_ARGS from wasi-sdk
- consolidate wasi-libc's plists, they have been identical after cmake
transition
- bump all existing WASI toolchain ports
Consumer PORTREVISIONs to be bumped 21.1.8_2 Charlie Li (vishwin) wasi: consistently use the wasm32-wasip1 triple
The WebAssembly community have reclaimed wasm32-wasi, without suffix,
for a future WASI 1.0 standard. The first version of WASI, 0.1, is
now wasm32-wasip1 in triple form, WASI 0.2 is wasm32-wasip2, etc.
Starting LLVM 22 the non-suffixed form is deprecated, aligning with
Rust and Go:
https://github.com/llvm/llvm-project/issues/165344
https://blog.rust-lang.org/2024/04/09/updates-to-rusts-wasi-targets/
The Mozilla build system's WASI checks always pass -Werror so
configure fails when the non-suffixed target/triple is passed using
LLVM 22:
