From ChangeLog
2016-12-12  Simon J. Gerraty  <sjg@bad.crufty.net>

	* Makefile (_MAKE_VERSION): 20161212
	  Merge with NetBSD make, pick up
          o main.c: look for obj.${MACHINE}-${MACHINE_ARCH} too.

2016-12-09  Simon J. Gerraty  <sjg@bad.crufty.net>

	* Makefile (_MAKE_VERSION): 20161209
	  Merge with NetBSD make, pick up
	  o main.c: cleanup setting of .OBJDIR
	  o parse.c: avoid coredump from (var)=val

2016-11-26  Simon J. Gerraty  <sjg@bad.crufty.net>

	* Makefile (_MAKE_VERSION): 20161126
	  Merge with NetBSD make, pick up
	  o make.c: Make_OODate: report src node name if path not set

2016-09-26  Simon J. Gerraty  <sjg@bad.crufty.net>

	* Makefile (_MAKE_VERSION): 20160926
	  Merge with NetBSD make, pick up
	  o support for .DELETE_ON_ERROR: (remove targets that fail)

2016-09-26  Simon J. Gerraty  <sjg@bad.crufty.net>

	* Makefile MAN: tweak .Dt to match ${PROG}

mk/ChangeLog

2016-12-12  Simon J. Gerraty  <sjg@bad.crufty.net>

	* install-mk (MK_VERSION): 20161212

	* meta2deps.py: set pid_cwd[pid] when we process 'C'hdir,
	rather than when we detect pid change.

2016-12-07  Simon J. Gerraty  <sjg@bad.crufty.net>

	* install-mk (MK_VERSION): 20161207

	* meta.stage.mk: add stage_as_and_symlink for staging packages.
	  We build foo.tgz stage_as foo-${VERSION}.tgz but want to be able
	  to use foo.tgz to reference the latest staged version - so we
	  make foo.tgz a symlink to it.
	  Using a target to do both operations ensures we stay in sync.

2016-11-26  Simon J. Gerraty  <sjg@bad.crufty.net>

	* install-mk (MK_VERSION): 20161126

	* dirdeps.mk: set DIRDEPS_CACHE before we include local.dirdeps.mk
	  so it can add dependencies.

2016-10-10  Simon J. Gerraty  <sjg@bad.crufty.net>

	* dirdeps.mk: set DEP_* before we expand .MAKE.DEPENDFILE_PREFERENCE
	  do that they can influence the result correctly.

	* dirdeps.mk (${DIRDEPS_CACHE}): make sure we pass on TARGET_SPEC

	* dirdeps.mk: Add ONLY_TARGET_SPEC_LIST and NOT_TARGET_SPEC_LIST
	  similar to ONLY_MACHINE_LIST and NOT_MACHINE_LIST

2016-10-05  Simon J. Gerraty  <sjg@bad.crufty.net>

	* dirdeps.mk: remove dependence on jot (normal situations anyway).
	  Before we read another Makefile.depend* set DEP_* vars from
	  _DEP_TARGET_SPEC in case it uses any of them with :=
	  When bootstrapping, trim any ,* from extention of chosen _src
	  Makefile.depend* to get the machine value we subst for.

2016-09-30  Simon J. Gerraty  <sjg@bad.crufty.net>

	* dirdeps.mk: use TARGET_SPEC_VARS to qualify components added to
	  DEP_SKIP_DIR and DEP_DIRDEPS_FILTER

	* sys.mk: extract some bits to sys.{debug,vars}.mk
	  for easier re-use by others.

2016-09-23  Simon Gerraty  <sjg@sjg-mba13>

	* lib.mk: Use ${PICO} for extension for PIC objects.
	  default to .pico (like NetBSD) safe on case insensitive filesystem.

2016-08-19  Simon J. Gerraty  <sjg@bad.crufty.net>

	* meta.sys.mk (META_COOKIE_TOUCH): use ${.OBJDIR}/${.TARGET:T} as default
