Steps to reproduce:

1. Log on to Raspberry Pi with latest raspbian (stretch)
2. Download https://repo.zabbix.com/zabbix/3.4/debian/pool/main/z/zabbix-release/zabbix-release_3.4-1+stretch_all.deb
3. `sudo dpkg -i zabbix-release_3.4-1+stretch_all.deb`
4. `sudo apt update`

Result:
Hit:1 http://archive.raspberrypi.org/debian stretch InRelease
Hit:2 http://raspbian.raspberrypi.org/raspbian stretch InRelease
Hit:3 http://repo.zabbix.com/zabbix/3.4/debian stretch InRelease

N: Skipping acquire of configured file 'main/binary-armhf/Packages' as repository 'http://repo.zabbix.com/zabbix/3.4/debian stretch InRelease' doesn't support architecture 'armhf'

{{ Expected:}}
No errors and to be able to install agent and proxy.

This has worked earlier in 2018 and the release package still exists and works.

Expectations:

I want either armhf fixed or a description and/or link to issue or page where the decision to stop supporting debian+armhf is decided.
