[feature request + question + bug] support for `cargo ndk -t x86_64 check`

I have a project that fails to build if not for android using the android NDK. So if I do cargo ndk -t x86_64 build it build. But since rust-analyzer uses cargo check to check for stuff, it crashes because the project is not buildable without the sdk.

I did cargo ndk -t x86_64 check and it works, returns 0 with all checked. I tried to set cargo ndk -t x86_64 check or ndk -t x86_64 check as the rust-analyzer checkOnSave command, but I get

[ERROR flycheck] Flycheck failed to run the following command: "cargo" "ndk -t x86_64 check" "--workspace" "--message-format=json" "--manifest-path" "/home/dev/project/glium_codename_app/Cargo.toml" "--target" "x86_64-linux-android" "--package=glium_codename" "--package=libcodename"
[ERROR rust_analyzer::lsp_utils] cargo check failed
Cargo watcher failed, the command produced no valid metadata (exit code: ExitStatus(unix_wait_status(25856))):
error: no such subcommand: `ndk -t x86_64 check`

Running myself the command:

cargo ndk -t x86_64 check --workspace --message-format=json --target x86_64-linux-android --package=glium_codename --package=libcodename

if I take out the -target x86_64-linux-android it works though. I don't know if some modification is needed on rust-analyzer or cargo-ndk.

No files or tests are named. Start by reproducing the rust-analyzer command and the working cargo ndk -t x86_64 check command, then determine whether command construction belongs in rust-analyzer or cargo-ndk. Done means the check command accepts rust-analyzer's workspace, metadata, manifest, package, and target arguments without duplicate-target or invalid-subcommand errors.
