Dear maintainers,

When compiling the package vtk9 for loong64 in the Debian Package Auto-Building environment [1], the error messages are as follows.

The full compilation log can be found at [2].

Please consider the patch I have attached.
The LoongArch architecture has been supported in the vtk upstream [3].
Would it be possible to include the support for LoongArch in the next upload?
If you have any questions, you can contact me at any time.
