This is a custom flag introduced by openwrt itself.
If the compiler has this flag set it does nothing apart from not throwing this warning/error.
If it isn't set, then the compiler will throw this message.
This message is only for tracking if the build of the package does include the TARGET_CFLAGS.
So this package doesn't honor all by openwrt buildroot defined cflags for the target and should be fixed.

Replaced with ubuntu 18.04 fixed.
