The build varies MAKEOBJDIRPREFIX at times which can make it difficult to track the original OBJROOT. This is easier when we get the original from env as SB_OBJROOT. If SB_OBJROOT did not come from env, set and export it the first time we set OBJROOT. This allows SB_OBJROOT to be used in .MAKE.META.IGNORE* variables to tweak what should be considered as making a target out-of-date. Update auto.obj.mk to latest from contrib/bmake - handles relative objdirs more simply and reliably. Also update jobs.mk and stage-install.sh Reviewed by: stevek Differential Revision: https://reviews.freebsd.org/D50313

# 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.
