WRONG!  While I've made the above work in -CURRENT, this still
doesn't work in RELENG_4 and shouldn't be relied upon.  From
<bsd.obj.mk>:

# MAKEOBJDIRPREFIX  Specifies somewhere other than /usr/obj to root the obj=
ect
#               tree.  Note: MAKEOBJDIRPREFIX is an *environment* variable
#               and works properly only if set as an environment variable,
#               not as a global or command line variable!
#
#               E.g. use `env MAKEOBJDIRPREFIX=3D/somewhere/obj make'

Compare:

$ pwd
/tmp/foo/src
$ MAKEOBJDIRPREFIX=3D/tmp/foo/obj make -f bsd.obj.mk -V .OBJDIR
/tmp/foo/obj/tmp/foo/src
$ make MAKEOBJDIRPREFIX=3D/tmp/foo/obj -f bsd.obj.mk -V .OBJDIR
/tmp/foo/src

Passing MAKEOBJDIRPREFIX as a command line variable with ``buildworld''
only works because make(1) enters all command line variables in
environment before starting any subprocesses.
