You can go on my forked, I added docker file to run the build inside docker as the solution for now

  docker run \
  --rm \
  -v $(pwd):/src \
  -u $(id -u):$(id -g) \
  emscripten/emsdk:2.0.26 \
  ./build.js

I think the fix would be to change the Makefile to use proper options syntax:

--- a/src/Makefile
+++ b/src/Makefile
@@ -475,8 +475,8 @@ ifeq ($(KERNEL),Darwin)
        CXXFLAGS += -mmacosx-version-min=10.14
        LDFLAGS += -mmacosx-version-min=10.14
        ifneq ($(arch),any)
-               CXXFLAGS += -arch $(arch)
-               LDFLAGS += -arch $(arch)
+               CXXFLAGS += -arch=$(arch)
+               LDFLAGS += -arch=$(arch)
        endif
        XCRUN = xcrun
 endif

However the fix above would bring you to the next error, which is CXXFLAGS += -mdynamic-no-pic being an unknown option for WASM architecture. Removing that solves the issue. Not sure how to make a patch to fix the latter properly.
