Hi! I am newbie to emscripten. When I use emmake to build a library, there 
are some errors that show lack of IPC libs. Then I check emsdk and find 
that there is a complete library of libc in the system folder, but the IPC 
target files is missing in libc.a of sysroot. Does emscripten not support 
IPC temporarily?  Or IPC can't run in wasm runtime?
```
