    build: better compliancy: mingw/cross/duktape

    - mingw defines __forceinline as extern - conflicts with static __forceinline,
      so just no-op __forceinline on platforms where we don't explicitly want it.
    - Some windows compilers (mingw) do have S_ISREG etc, so don't redefine those
      blindly for Windows.
    - mingw has a convention of lower-case file names, so it fails to link with
      Userenv.lib when cross compiling on Linux. Use lower case instead.
      On Windows it doesn't matter since it's case-insensitive anyway.
    - uv_get_data: use correct pointer at duk_get_lstring, possibly coerce later.
