As we build a single statically linked bunary for WASM, we will end up
with just one copy of each function in it. Both LO core and Poco
include expat. Upstream Poco builds one of the expat source files as
C++. That causes trouble as it then isn't compatible with what LO core
wants to call. Or something like that. You get "RuntimeError: null
function or function signature mismatch". (The "signature" concept in
WASM is orthogonal to C++ name mangling.)
