  1. Patch reverts upstream commit:
  2. https://github.com/collectd/collectd/commit/6124da7a48f28f54fc09ebeb942d1037516fe6ab
  3. The commit changed the detection path due to FreeBSD issues,
  4. but apparently affects also Openwrt buildroot negatively.
  5. Original explanation:
  6. From 6124da7a48f28f54fc09ebeb942d1037516fe6ab Mon Sep 17 00:00:00 2001
  7. Subject: [PATCH] Fix libmodbus detection on FreeBSD
  8. We look for modbus/modbus.h in /usr/local/include/modbus
  9. but we should look for modbus.h
  10. This is only an issue on FreeBSD since /usr/local/include is not
  11. in the default search path.
