+-   Not too long after the above, Emscripten 2.0.10 doesn't export `dynCall()`

+    put in place that uses `dynCall()` internals, which should be present
+    always.

+               CMake 3.13-only features and a ton of backslashes:

+               (the ${xylophone} is needed because CMake expands that to
+               `\$${xylophone}dynCall` for some reason, which then the shell
+               collapses to `$dynCall` (assuming a $xylophone env var doesn't
+               exist, which it shoulndn't, but also it's 2021 and so everything
+               is possible), and no amount of \\\\$$$ helps avoiding that
+               xylophone); but doing so means we forever hardcode what
+               functions are exported and thus whatever extra Emscripten needs
+               to export will be overriden by this, causing only pain and
+               misery.
+
+               So instead we rely on the implementation details of dynCall,
+               which are actually really simple:
