Build error on Poky Styhead when using Fluentbit 3.1.6

[nortenorte]

Bug Report

Describe the bug
We are staying on Fluentbit v3.1.6 because issue described in: #9664

Our build system was upgraded to Poky Styhead which changes compiler default to treat some warnings as errors, which previous compiler versions didn't. Compiler now checks incompatible-pointer-types which Fluentbit 3.1.6 creates warnings for.

Workaround for AARCH64-based hardware ,does not seem to other ARM-based hardware, update .bb-file:
EXTRA_OECMAKE += "-DCMAKE_C_FLAGS='-Wno-incompatible-pointer-types' -DCMAKE_CXX_FLAGS='-Wno-incompatible-pointer-types' "

To Reproduce
Build options in .bb-file:

# Disable LuaJIT and filter_lua support
EXTRA_OECMAKE += "-DFLB_LUAJIT=Off -DFLB_FILTER_LUA=Off "

# Disable Library and examples

Updated workaround to build all target:
Instead of EXTRA_OECMAKE += ...
Use
CFLAGS += "-Wno-error=incompatible-pointer-types "
