See [forum:/forumpost/91811439aa|forum post 91811439aa] for the complaint
that prompted me to take down this demonstration code. I have other things
to do rather than argue about posts such as the foregoing, so it is easier
to just take the code down. If you need this code, you can downloading older
check-ins. The beauty of DAG-based version control systems like Fossil
(and Git) is that nothing is ever lost; it is just stops appearing on
trunk.

Overhaul the wasm build to (A) support more coexisting variants, e.g. 32/64-bit of both vanilla and esm, and (B) build each variant to its own subdir so that they can build in parallel. It can, with make -j4, now build all new variants in half the time it previously took for just the 32-bit builds. The new build logging output, though unconventional, serves two purposes: (A) improve my build-time situational awareness and (B) it help demystify some of the build steps and output files.
