This can be disabled by putting WITHOUT_AUTO_OBJ=yes in /etc/src-env.conf, not /etc/src.conf, or passing it in the environment. The purpose of this rather than simply flipping the default of AUTO_OBJ to yes is to avoid hassling users with auto.obj.mk failures if the wanted OBJDIR is not writable. It will fallback to writing to the source directory like it does today if MAKEOBJDIRPREFIX is not writable. The act of enabling MK_AUTO_OBJ disables all 'make obj' treewalks since previous work has made those not run if MK_AUTO_OBJ==yes in Makefile.inc1.
