# $FreeBSD$
#
# Early setup of MAKEOBJDIR
#
# Default format is: /usr/obj/usr/src/[${TARGET}.${TARGET_ARCH}/]bin/sh
# MAKEOBJDIRPREFIX is /usr/obj
# OBJROOT is /usr/obj/usr/src/
# OBJTOP is /usr/obj/usr/src/[${TARGET}.${TARGET_ARCH}/]
# MAKEOBJDIR is /usr/obj/usr/src/[${TARGET}.${TARGET_ARCH}/]bin/sh
#
# MAKEOBJDIRPREFIX will override the default pattern above and internally
# set MAKEOBJDIR. If OBJROOT is set then MAKEOBJDIRPREFIX is rooted inside
# of there.
#
# If MK_UNIFIED_OBJDIR is no then OBJROOT will always match OBJTOP.
#
# If .MAKE.LEVEL == 0 then the TARGET.TARGET_ARCH is potentially added on.
# If .MAKE.LEVEL > 0 and MAKEOBJDIRPREFIX is set then it will not get
# TARGET.TARGET_ARCH added in as it assumes that MAKEOBJDIRPREFIX is
# nested in the existing OBJTOP with TARGET.TARGET_ARCH in it.
#
# The expected OBJDIR is stored in __objdir for auto.obj.mk to use.
#
# AUTO_OBJ is opportunistically enabled if the computed .OBJDIR is writable
# by the current user. Some top-level targets disable this behavior in
# Makefile.sys.inc.
