Can't compilate with Emscripten (Windows 11)

[liudonghua123]

I tried to make a web assembly build of mame, I installed and configured the latest emsdk 3.1.18. However when I tried emmake make SUBTARGET=arcade, it failed with make: *** [makefile:1266: build/projects/sdl/mamearcade/gmake-asmjs/Makefile] Error -1 error.

Building with Emscripten under a Windows environment is not currently supported - it should work in Linux.
