Modified Files:
	src/usr.bin/make: main.c make.1 pathnames.h

Log Message:
Deprecate support for automagically setting the .OBJDIR to
	./obj.${MACHINE}
	./obj
	/usr/obj/${PWD}

The rules for the default .OBJDIR setting are now simplified to
(and documented as) trying the chdir to the following
(if the appropriate variable is defined):
	${MAKEOBJDIRPREFIX}${.CURDIR}
	${MAKEOBJDIR}
	${.CURDIR}

.OBJDIR can be overridden in the makefile.
<bsd.obj.mk> uses this to provide the "culled" .OBJDIR semantics
for NetBSD's /usr/src builds.

MAKEOBJDIRPREFIX & MAKEOBJDIR still can only be provided
in the environment or on make(1)'s command line.

Per discussion on tech-toolchain.
This should reduce a lot of lossage people have experienced over
the years with various .OBJDIR setups.
