[MinGW] Implicitly add .exe suffix if not provided GCC implicitly adds an .exe suffix if it is given an output file name, but the file name doesn't contain a suffix, and there are certain users of GCC that rely on this behaviour (and run into issues when trying to use Clang instead of GCC). And MSVC's cl.exe also does the same (but not link.exe). However, GCC only does this when actually running on windows, not when operating as a cross compiler. As GCC doesn't have this behaviour when cross compiling, we definitely shouldn't introduce the behaviour in such cases (as it would break at least as many cases as this fixes).
