Please consider the patch I have attached.
If you need additional information or have problems with the patch, you can contact me at any time.
Referring to other architectures and add loongarch64 architecture support for lintian, some example are given below:
- Add loong64 support to the data/architectures/host.json file.
+      "loong64" : {
+         "DEB_HOST_ARCH" : "loong64",
+         "DEB_HOST_ARCH_ABI" : "base",
+         "DEB_HOST_ARCH_BITS" : "64",
+         "DEB_HOST_ARCH_CPU" : "loong64",
+         "DEB_HOST_ARCH_ENDIAN" : "little",
+         "DEB_HOST_ARCH_LIBC" : "gnu",
+         "DEB_HOST_ARCH_OS" : "linux",
+         "DEB_HOST_GNU_CPU" : "loongarch64",
+         "DEB_HOST_GNU_SYSTEM" : "linux-gnu",
+         "DEB_HOST_GNU_TYPE" : "loongarch64-linux-gnu",
+         "DEB_HOST_MULTIARCH" : "loongarch64-linux-gnu"
+      },

- Add loong64 support to the data/buildflags/hardening.json file.
+      "loong64" : [
+         "bindnow",
+         "format",
+         "fortify",
+         "pie",
+         "relro",
+         "stackprotector",
+         "stackprotectorstrong"
+      ],

thanks,
Dandan Zhang
