Can't check kernel version on arm64 systems

[Jaap Winius]

Hi folks,

My systems mostly run the Debian 11 xymon-client and hobbit-plugins  
packages for amd64 and armhf. However, I've now got a few arm64  
systems (for the Odroid N2+) and have run into a problem. After  
installing a few missing dependencies for this architecture  
(libyaml-tiny-perl, libfile-slurp-perl and lsof), the libs check now  
says:

Couldn't check for string '4.9.277-arm64' in  
/boot/vmlinuz-4.9.277-arm64. Can't check kernel version!

Seeing as there's nothing wrong with my systems, how can I get Xymon  
to ignore this issue, or better yet, run the kernel version properly?

Thanks,

Jaap
