QGroundControl Android build failing at linking stage with undefined C++ standard library symbols (__cxa_guard_acquire, operator new/delete, vtable symbols, etc.) using NDK 27.2.12479018 and Qt 6.10.0 for arm64-v8a. The linker can’t find libc++ symbols despite using -stdlib=libc++ flag. Looking for solutions to properly link the C++ standard library.
