Dear maintainers,
The protobuf package was built on loong64.
But I found that there is a lack of loongarch64 support in
src/google/protobuf.
If the support for loong64 is missing in protobuf, packages that
build-depend on protobuf will fail to build, for example,
Compiling the justbuild(Need to add loongarch64 support first) failed
for loong64.
The build error log is as follows,
```
......

```
Please consider the patch I attached for protobuf.
Based on attached patch, I have built protobuf successfully on locally.
Based on local libprotobuf-dev, I have built justbuild(Need to add
loongarch64 support first. I have submitted patch to justbuild source
pacakge) successfully on locally.

Please add loongarch64 support in protobuf.
Your opinions are welcome.
