[Pkg-rust-maintainers] Bug#1060910: rust-cty: fails to build rust-cty on loong64

[WANG Rui]

Source: rust-cty
Version: 0.2.1-1
Severity: normal

Dear Maintainer,

I am the maintainer for the Rust LoongArch target, and I am reporting a build
failure issue with `rust-cty` on LoongArch64. I am seeking your assistance in
addressing this issue.

I am aware that the build failure is due to the lack of LoongArch support in
`cty`. Previously, I attempted to submit a pull request to the upstream `cty`
project to address the issue. However, the project is no longer maintained, so
I kindly request your help in incorporating a fix patch into the Debian project.
The fix is a single line of code.
