From bf917b585281f36dcd0b77776310bbed3d2afa75 Mon Sep 17 00:00:00 2001

Subject: .TARGETOBJDIR has been removed from make and CANONICALOBJDIR set in
 bsd.obj.mk.  Also, a make target called objwarn checks to see if ${.OBJDIR}
 != ${.CURDIR} and ${.OBJDIR} != ${CANONICALOBJDIR} and outputs a warning. 
 (No warning for the latter if MAKEOBJDIR or MAKEOBJDIRP REFIX is set). 
 objwarn is called from all targets in bsd.prog.mk, bsd.kmod.mk, and
 bsd.lib.mk.
