Your mk.conf can use .if defined(BSD_PKG_MK) to apply different 
settings for pkgsrc.

MAKEOBJDIRPREFIX works only on the command line or in the 
environment, because make(1) processes it before reading any 
Makefiles.  This is documented in the make(1) man page; search for 
.OBJDIR.

If MAKEOBJDIRPREFIX is not set in the environment or on the 
command line, then make(1) itself won't use it; but if it's set in 
mk.conf then parts of bsd.*.mk will see that it's defined and will 
assume that make(1) has used it.  This inconsistency can easily 
lead to problems in bsd.obj.mk.  I am a little surprised that this 
didn't cause trouble for you before now.
