- Patch reverts upstream commit:
- https://github.com/collectd/collectd/commit/6124da7a48f28f54fc09ebeb942d1037516fe6ab
-
- The commit changed the detection path due to FreeBSD issues,
- but apparently affects also Openwrt buildroot negatively.

- Original explanation:
- From 6124da7a48f28f54fc09ebeb942d1037516fe6ab Mon Sep 17 00:00:00 2001
- Subject: [PATCH] Fix libmodbus detection on FreeBSD
-
- We look for modbus/modbus.h in /usr/local/include/modbus
- but we should look for modbus.h
-
- This is only an issue on FreeBSD since /usr/local/include is not
- in the default search path.
