Makefile: lto: Pass -warn-stack-size only on LLD < 13.0.0
Since LLVM commit fc018eb, the '-warn-stack-size' flag has been dropped [1], leading to the following error message when building with Clang-13 and LLD-13: ld.lld: error: -plugin-opt=-: ld.lld: Unknown command line argument '-warn-stack-size=2048'. Try: 'ld.lld --help' ld.lld: Did you mean '--asan-stack=2048'? In the same way as with commit 2398ce80 ("x86, lto: Pass -stack-alignment only on LLD < 13.0.0") , make '-warn-stack-size' conditional on LLD < 13.0.0.
