Gopy support for ARM based Macbooks

Hi,
I am trying to use gopy to create a python package but I keep encountering the same error when running the last command in `make build`. The error I get is
`
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
`
I am wondering whether there is currently support for ARM based macbooks. I have tried adding `-target arm64-apple-darwin` to the `CLANG` in the `Makefile`, but am still getting this issue.
Thanks for your time.

首先检查 Makefile 中的 CLANG 设置，并在基于 ARM 的 Mac 上复现最终的 `make build` 命令。当 arm64 链接器错误得到解决，并且 gopy 能在该平台上成功创建 Python 包时，即表示完成。
