feat: add basic loongarch64 support
- Refactor the repo code to merge
- Use standard toolchain
- Fix the compile command
I will submit other code about interrupt soon.
@hky1999 Support for la64 is now complete. Except for the two applications redis and sqlite, which were not tested, other apps have passed. If you have time, please check to see if there are any areas for improvement.
Thanks for your contribution! Are you still available? Let’s work on merging this PR.
I will fix these errors.
@equation314 Do you have time to check and see if there are any other problems?
Thanks! Please fix conflicts and CI.
@equation314 This CI error may be due to a rust version issue. I'm not very familiar with CI, but it seems that the latest version of rust is used in CI.

Hello, CI should fit the latest version of Rust, currently I believe it should be rust version 1.77.0-nightly (bf8716f1c 2023-12-24).
Some warnings like this should be fixed.

I try to build this branch tonight.
