> Setting DBG=-g in the environment should do it.
   
   To not strip the installed binaries, you can set STRIPFLAG to ""
   (empty) in the environment. That's not strictly necessary, as long as
   you retain the unstripped binaries in the object directories, as you
   can use them to debug core dumps or even live processes launched with
   the stripped binaries, the running image being the same.


you may want to set DBG="-g -O0" to avoid any optimisation.
