`Cargo doc` failed on windows.

I want to build documentation locally on my windows, so I just copy-paste the command in https://github.com/uutils/uutils.github.io.
But it failed as follows:

warning: output filename collision.
The lib target `stdbuf` in package `uu_stdbuf_libstdbuf v0.2.2 (D:\msys2\home\test\src\coreutils-main\src\uu\stdbuf\src\libstdbuf)` has the same output filename as the bin target `stdbuf` in package `uu_stdbuf v0.2.2 (D:\msys2\home\test\src\coreutils-main\src\uu\stdbuf)`.
Colliding filename is: D:\msys2\home\test\src\coreutils-main\target\doc\stdbuf\index.html
The targets should have unique names.
This is a known bug where multiple crates with the same name use
the same path; see <https://github.com/rust-lang/cargo/issues/6313>.

   = help: if you wanted to use a crate named `platform`, use `cargo add platform` to add it to your `Cargo.toml`

I don't know much about how rustdoc works, so I just adjust the command trying not to include the stdbuf:

cargo doc --no-deps -F default --workspace

But it still failed for the same reason.

Start by reproducing the reported cargo doc --workspace failure on Windows and inspect src/uu/stdbuf/build.rs around line 92, where platform::DYLIB_EXT is unresolved. Compare the documentation command with the stdbuf library and binary targets. Done means the documented command completes without the unresolved platform error or the reported output collision.
