Huang Qi 5048d6b472 tools: Add essential math.h for wasm build ... If the experimental feature Wasm build enabled with multi thread compiling, the COPYFILE (cp) maybe raise the error below: ``` cp: cannot create regular file 'math.h': file exists ``` This error cause by that the wasi-sdk don't provide the math.h for non-wasi envrioment, for this case, provide a math.h for it instead of copy file each time is better.
