Hi Milan, just to be sure:
Are you doing a multi-stage build? On which stage is the warning emitted? The architecture you are building on itself is ARM or are you doing cross compilation? The argument itself is a compatibility-option for GCC, which might be added after clang-11 was branched? (https://github.com/llvm/llvm-project/commit/0ee176edc8b4a6f20527e907bfd026b07a27e7ef seems to have it included though!) The generic warning message is emitted when that specified option is not utilized because it does not apply in this instance. For example, I have seen this when compiling C code with C++-specific arguments. So your specific setup would be relevant to know.
