Bug#1054525: vtk9: Please add support for loongarch64

[zhangdandan]

Source: vtk9
Version: 9.1.0+really9.1.0+dfsg2-7
Severity: wishlist
Tags: ftbfs patch
User: debian-loongarch at lists.debian.org
Usertags: loong64

Dear maintainers,

When compiling the package vtk9 for loong64 in the Debian Package 
Auto-Building environment [1], the error messages are as follows.
......Omit
/<<PKGBUILDDIR>>/Utilities/KWIML/vtkkwiml/include/kwiml/abi.h:476:3: 
error: #error "Byte order of target CPU unknown."
   476 | # error "Byte order of target CPU unknown."
       |   ^~~~~
......Omit

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.
