the etc Makefile override that by putting USETOOLS into $.MAKEOVERRIDES This way the default for kernel compiles is still to use the installed toolchain instead of depending on $TOOLDIR. $TOOLDIR can be used by simply adding USETOOLS=yes to the command line as usual. Adjust each ports template to set the default no setting and also pull in bsd.own.mk if they weren't already to ensure they'll build correctly with the new toolchain setup.
