In most "normal" usage you will likely not notice a difference.
It is only when a makefile is "being clever" that things go south when
you break its expectations.

The check in src/Makefile is only guarding against MAKEOBJDIRPREFIX set
in say make.conf, it explicitly discards the possibility of setting
MAKEOBJDIRPREFIX on command line - which seems wrong.

Also with bmake, you *can* usefully set MAKEOBJDIRPREFIX in a makefile
since the choice of .OBJDIR can be made after make starts reading

So the current test is perhaps out dated on that score too - though
only if something like auto.obj.mk is being used (-DWITH_AUTO_OBJ)
which I don't think I've tested with buildworld.
