Not according to "/usr/share/mk/bsd.README" which I quote:

MKOBJDIRS	If "no", don't create objdirs during a "make build".
		"no" by default.

$ cd /usr/share/mk
$ grep -n MKOBJDIRS *.mk
bsd.own.mk:408:MKOBJDIRS:=      no

Thank you.  I'll remove "OBJMACHINE" from "/etc/mk.conf".

Thank you.  I'll remove TOOLDIR from "/etc/mk.conf".

Thank you.  I'll definately implement this.

Thank you.  I'll remove RELEASEDIR from "/etc/mk.conf".
