I have uploaded my config.site override to https://gist.github.com/tiran/5ccffa28723d3e4739db848451bd9efa . It contains overrides based on pyodide and overrides for new features.

I'm also getting this error with emscripten 2.0.13. _sys_shutdown is the syscall for shutdown(2) used by the socket module.

error: undefined symbol: __sys_shutdown (referenced by top-level compiled C/C++ code)
warning: Link with `-s LLD_REPORT_UNDEFINED` to get more information on undefined symbols
warning: To disable errors for undefined symbols use `-s ERROR_ON_UNDEFINED_SYMBOLS=0`
warning: ___sys_shutdown may need to be added to EXPORTED_FUNCTIONS if it arrives from a system library
Error: Aborting compilation due to previous errors
