Dear maintainers,
The reptyr source package lacks LoongArch64 architecture support.
I have added support for loongarch64 in reptyr package and built
successfully on my local ENV.
Please consider the patch I attached.
The support for loongarch64 since python3.* in the Debian Package
Auto-Building environment.
I modify the PYTHON_CMD version in Makefile locally.

```
Please consider to update the PYTHON_CMD version in reptyr source package.
Could you add loongarch64 support in the next upload?
Your opinions are welcome.
Thanks
Dandan Zhang
