Presence of __malloc_hook is explicitly tested by the autoconf script;
line 593 of configure.ac in my local tree.

It won't attempt to use it unless that tests passes; does the
emscriptem stuff run the configuration tests in the correct target
environment? Are you overriding the build system?

It's not clear to me why its failing.
