[Potential Bug] CMake build fails: NDK r27 downloads x86_64 binaries instead of aarch64 on ARM64 host

[AquilleTech]

Environment:

• App Name/Version: RV2IDE
• Device Host Architecture: ARM64 (aarch64)
• NDK Version: 27.0.12077973
• Build System: Gradle + CMake 4.1.x

Description:
When compiling a C/C++ (CMake) enabled Android project on an ARM64 Android device using RV2IDE, the build fails during :app:configureCMakeDebug.
The installed NDK directory under android-sdk/ndk/27.0.12077973/toolchains/llvm/prebuilt/ contains linux-x86_64 instead of a native aarch64 prebuilt binary/directory. Because of this, CMake cannot locate the executable clang / clang++ compiler binaries at prebuilt/bin/clang.

Steps to Reproduce:

• Open a project with C/C++ support (CMake) in RV2IDE on an ARM64 Android device.
• Ensure NDK 27.0.12077973 is selected/installed.
• Run ./gradlew :app:assembleDebug.
• Inspect the directory:
  cd /data/user/0/com.tom.rv2ide/files/home/android-sdk/ndk/27.0.12077973/toolchains/llvm/prebuilt/
• Run ls -la and observe that only linux-x86_64 exists.

Expected Behavior:
The SDK Manager should either:

• Download/provide an NDK build compiled natively for aarch64 (ARM64 Android host).
• Automatically create symlinks pointing to the internal native clang/clang++ toolchain (e.g., /data/data/com.tom.rv2ide/files/usr/bin/clang).

Actual Behavior:
CMake fails with the following log:
C/C++: CMake Error at CMakeLists.txt:3 (project):
C/C++: The CMAKE_C_COMPILER:
C/C++: /data/user/0/com.tom.rv2ide/files/home/android-sdk/ndk/27.0.12077973/toolchains/llvm/prebuilt/bin/clang
C/C++: is not a full path to an existing compiler tool.
