Historically, Rust's Fuchsia targets have been labeled x86_64-fuchsia and aarch64-fuchsia. However, they should technically contain vendor information. This CL changes Fuchsia's target triples to include the "unknown" vendor since Clang now does normalization and handles all triple spellings. This was previously attempted in #90510, which was closed due to inactivity.
rustc_target contains some very low-level details that are
specific to different compilation targets and so forth.
For more information about how rustc works, see the rustc dev guide.
