Fixed bug 3761 - Windows non-MinGW cmake build defines HAVE_WCSLCPY and HAVE_WCSLCAT

https://github.com/SDL-mirror/SDL/commit/0f0ad62237fabb58d5811fe6fa59e5e5aa0e2fb5 (git head at the time of writing); Visual Studio 2015, toolset v140, Platform 10.0.14393.0, building for x64

Windows non-MinGW cmake build sets defines implying wcslcpy and wcslcat are available, but Windows doesn't have these functions.

That's weird, these are the exact two functions that Emscripten incorrectly believed it had until we upgraded the buildbot's emsdk install.

Not sure what's up with this, but it's possibly not a MingW-specific thing!
