[Mono-ue] Build Error

rc.exe is the MS resource compiler. It looks like it doesn't like some
of the arguments we're passing it via UBT. My guess is that it's the
string constants we're passing in via the Defines list (see
MonoRuntime/Source/ThirdParty/mono/EmbeddedMono.Build.cs), since C++
compilers (and related tools) tend to be pretty finicky about those.
Maybe some characters in your path are breaking the escaping or

In the latter case, the missing overrides, it looks like you haven't
applied the engine patchset.
