Enable a default native ARCH uses a posix compatible script to find the native arch. (based on ppigazzini's https://github.com/ppigazzini/stockfish-downloader ) use that native arch by default, no changes if ARCH is specified explicitly. SF can now be compiled in an optimal way simply using make -j profile-build closes https://github.com/official-stockfish/Stockfish/pull/4777 No functional change
