No, you misinterpreted the check (please see below).

Repeat ten times today: MAKEOBJDIRPREFIX is an environment variable,
and works properly only if set as environment variable, not as a
command-line variable or a global variable (in /etc/make.conf).
This is now documented in the following sources:
- make(1) manpage
- make.conf(5) manpage
- anti-footshooting measure in /usr/src/Makefile
Rumors are that this is probably now the best documented feature
of BSD make(1). ;)
