This simply what src/Makefile says to do, and AFAIK it has been that way
for ages.
Since delete-old is in TGTS it gets run via:
#
# Handle the user-driven targets, using the source relative mk files.
#
${TGTS}:
${_+_}@cd ${.CURDIR}; ${_MAKE} ${.TARGET}
and
$ make -dV -V _MAKE
PATH=${PATH} ${BINMAKE} -f Makefile.inc1 TARGET=${_TARGET} TARGET_ARCH=${_TARGET_ARCH}
$ make -dV -V BINMAKE
`if [ -x ${MAKEPATH}/make ]; then echo ${MAKEPATH}/make; else echo
${MAKE}; fi` -m ${.CURDIR}/share/mk
$ make -V _MAKE
PATH=/sbin:/bin:/usr/sbin:/usr/bin `if [ -x
/var/obj/current/b/sjg/work/FreeBSD/current/src/make.amd64/make ]; then
echo /var/obj/current/b/sjg/work/FreeBSD/current/src/make.amd64/make;
else echo make; fi` -m /b/sjg/work/FreeBSD/current/src/share/mk -f
Makefile.inc1 TARGET=amd64 TARGET_ARCH=amd64
$
Now you may be right that that's a bad idea, but it isn't anything new.
