The 'target' is only used for compilers (if 'a.exe' is a compiler, then it would produce code for 'target', which might not be the same as 'build' and 'host').
If you build 'a.exe' with the GNU build system, then: 'build' is this macOS, and can usually be guessed, and 'host' is where 'a.exe' will run, and is typically specified by `--host=`, and 'target' is meaningless for something not a compiler. For the 'i686-w64-mingw32-gcc' program: 'build' is unknown, and 'host' is this macOS, and 'target' is where 'a.exe' will run.The rule of thumb is that `--host=` is usually the only option required to cross-compile something (cross-compiling a compiler would require an addition `--target=`). The compiler is not different from this point of view.
