Description
HOST OS: macOS Sonoma 14.3
I'm currently trying to build matrix-sdk-crypto-ffi on main branch with:
cargo build --target=aarch64-linux-android
And I get the following error log:
warning: libsqlite3-sys@0.28.0: Compiler family detection failed due to error: ToolNotFound: Failed to find tool. Is `aarch64-linux-android-clang` installed?
error: failed to run custom build command for `libsqlite3-sys v0.28.0`
Caused by:
process didn't exit successfully: `/Users/natycaldas/Documents/matrix-rust-sdk/target/debug/build/libsqlite3-sys-e5814bfbabc10d7a/build-script-build` (exit status: 1)

My ~/.cargo/config.toml has the following key
[target.aarch64-linux-android]
linker = "/opt/homebrew/Caskroom/android-ndk/27b/AndroidNDK12297006.app/Contents/NDK/toolchains/llvm/prebuilt/darwin-x86_64/bin/aarch64-linux-android35-clang"

Research direction
Start with ~/.cargo/config.toml and reproduce the cargo build --target=aarch64-linux-android command for matrix-sdk-crypto-ffi. Compare the configured Android linker with the tool expected by libsqlite3-sys; done means the Android target builds without the missing aarch64-linux-android-clang error.
