I don't see any way for this to be called, but I note that this behavior is tied to

cpython/Tools/wasm/wasi.py

Line 216 in e9556e1

pydebug = lib_dir.endswith("-pydebug")

I think this aspect of the WASM build is broken, and if this code can be deleted then perhaps that trail can too.

return pybuilddir
