You can also build this program with WASI, but we need to make some changes to wasi-sysroot:
1. disable malloc / free of wasi as they don't support shared memory
1. disable malloc/free of wasi if the wasi-sdk version is smaller than wasi-sdk-12.0 (not include 12.0), as they don't support shared memory:
``` bash
/opt/wasi-sdk/bin/llvm-ar -d /opt/wasi-sdk/share/wasi-sysroot/lib/wasm32-wasi/libc.a dlmalloc.o

## Known limits
- `pthread_attr_t`, `pthread_mutexattr_t` and `pthread_condattr_t` are not supported yet, so please pass `NULL` as the second argument of `pthread_create`, `pthread_mutex_init` and `pthread_cond_init`.
- The `errno.o` in wasi-sysroot is not compatible with this feature, so using errno in multi-thread may cause unexpected behavior.
- Currently `struct timespec` is not supported, so the prototype of `pthread_cond_timedwait` is different from the native one, it takes an unsigned int argument `useconds` to indicate the waiting time.
