How to enable sigchase query option in bind-dig

Hi everyone,

does anyone know how to enable +sigchase option in bind-dig? by default there's no sigchase option defined. I read in

that such a setting STD_CDEFINES="-DDIG_SIGCHASE=1" during compilation needs to be added. However after amending the Makefile and Building the bind package my problem is still there.
any idea how to solve this issue?
