Fix Makefile for Android NDK cross-compile For cross-compiling to Android on windows, the Makefile needs some tweaks. Tested with Android NDK 23.1.7779620 and 21.4.7075529, using Windows 10 with clean MSYS2 environment (i.e. no MINGW/GCC/Clang toolchain in PATH) and Fedora 35, with build target: build ARCH=armv8 COMP=ndk The resulting binary runs fine inside Droidfish on my Samsung Galaxy Note20 Ultra and Samsung Galaxy Tab S7+ Other builds tested to exclude regressions: MINGW64/Clang64 build on Windows; MINGW64 cross build, native Clang and GCC builds on Fedora. wiki docs https://github.com/glinscott/fishtest/wiki/Cross-compiling-Stockfish-for-Android-on-Windows-and-Linux closes https://github.com/official-stockfish/Stockfish/pull/3901 No functional change
