I haven't dived into Mojave yet, but if all the system libraries in /usr/lib and all the Frameworks are x86_64 only, then I don't see how that could work, even if you compiled against an SDK (like the 10.13 SDK) that still has i386 support.
Even gcc links into the system libs for lots of it's underpinnings. K
