Just point them to the make files and have them compile it,
I personally I am more happy if you offer a .tar.gz build that I can run without root then a .deb . It happened that someone had a .deb ut I did not trust them, so I unpacked the .deb and runt he application directly.
Anyway if you don't have a Linux system and your program is open source then the useers should contribute packages. For closed source programs then you are fine with a cross distro method, like I seen small games made with Unity,Unreal,RenPy,RPG Maker that are also packagted for linux into a .zip archive and nobody complained and asked for special packages.
There are assholes Linux users out-there but is the same in all communities where you have entitled people that think their opinions are the truth.
