ac4a4f140e Per weak consensus on this topic, remove suggestion to set
HISTORICAL_MAKE_WORLD from the text that's output.  This was committed
against the previous consensus.  Leave the documentation in this file
as a compromose.  The HISTORICAL_MAKE_WORLD knob is intentionally
obfuscated and we only trust people smart enough to read the Makefile
to use it.  All others have no business using it due to its danger,
unless DESTDIR is set.

fb55e85566 Simply running ``make world'' will bomb unless you dig up the
undocumented HISTORICAL_MAKE_WORLD variable and set it.  Note it
here so the blow up will not really be a surprise to people who
read.

621e4ae168 Create a new target 'buildenvvars'. This target reports the build
environment for cross building (the same one you'd get interactively
in make buildenv).  This cannot be a simple

        make -f Makefile.inc1 -V WMAKEENV

because in PATH is not set correctly unless one takes a trip through
the Makefile/Makefile.inc1 indirection, the logic of which is too
large to reproduce outside of Makefiles.

e2a3608153 Add delete-old and delete-old-libs targets:
- removes obsolete files/dirs or libraries.
  - works in interactive (default) and batch mode
  - respects DISTDIR
  - documented in UPDATING and build(7)

The head of the file ObsoleteFiles.inc contains instructions how to add
obsolete files/dirs/libs to the list. Obviously one should add obsolete
files to this list, when he removes a file/dir/lib from the basesystem.

Additionally add check-old target:
  - allows re@ to check if a file on the obsolete list resurfaces

Design goals:
  - allows full control by the user (default interactive mode)
  - possibility of scripted removal of obsolete files (batch mode)
  - opt-in removal of files (explicit list of files)
  - seperate removal of libs (2 delete targets)

Important design decissions:
  - structured list of files to remove instead of a plain text file:
    * allows to remove additional files if a NO_foo knob is specified
      without the need to change the targets (no NO_foo knob is respected
      yet)
  - not using mtree like NetBSD does:
    * mtree doesn't has an interactive mode

dd0f39233c - Embed the "buildkernels" target into the "universe" target so that
the "make -n universe" output looks more builder (human) friendly.

- Wrap the "universe" target into a ".if make(universe)"; it's only
  intended to be called directly so it should be safe to do it.

012a8b3f81 Repo-copy tools/regression/usr.bin/make to tools/build/make_check
and adjust the path in the Makefile for the upgrade_checks target.
These checks are really feature upgrade checks that should be fast
and just find out whether we need to build a new make before
proceeding with other targets like buildworld. This makes the
place free for a real regression test suite in the old place.

e9bddef1f0 Previous revision didn't fix all cases. For example,
testing for variables that are always defined (e.g.,
"make -V CC") would still print a false warning.  Fix
this by only passing a submake the MAKEOBJDIRPREFIX=*
argument if it was present.  As a result, we loose
the check for -DMAKEOBJDIRPREFIX, or an esoteric
"MAKEOBJDIRPREFIX = foo" (with embedded spaces), but
these are unorthodox enough to not care about them.

The make(1) bug mentioned in the previous revision
was just fixed in make/main.c,v 1.109.

26e8ef3fe8 Unbreak the MAKEOBJDIRPREFIX variable check by avoiding bugs in make(1).
When make flags are passed to make in the environment, the string is
chopped up in an (argc,argv) vector. This happens in brk_string() and
the chopped up string is stored in static buffer. When this includes
something like "-V BINMAKE", then a pointer into the static buffer is
put on the variables list for evaluation later. However, brk_string()
is used for more than just chopping up the MAKEFLAGS env. variable, so
it's very likely that the static buffer is clobbered. In fact, this is
exactly what happens.
The result is that _MAKEOBJDIRPREFIX gets assigned whatever garbage
the child make happens to emit, causing the test to fail. Like this:

pluto2% cd /usr/src
pluto2% make -V BINMAKE
"/q/6.x/src/Makefile", line 94: MAKEOBJDIRPREFIX can only be set in environment, not as a global (in /etc/make.conf) or command-line variable.
pluto2% make -dv -V BINMAKE | & grep _MAKEOBJDIRPREFIX
Global:_MAKEOBJDIRPREFIX = }

The fix is to not use MAKEFLAGS for this, but simple pass the flags
as arguments. Ideally make(1) should be fixed but that's beyond the
scope of my attention span.

This fixes release.

1d9468ee37 Convert tools/lib32/build.sh into world connectable hooks. This still
rates pretty high on the "hack!" scale, but it works for me.  Adding
-DWANT_LIB32 to the world build command line, or 'WANT_LIB32=yes' to
/etc/make.conf will include the 32 bit libraries with the build.

I have not made this default behavior.  Cross compiling this stuff is an
adventure I have not investigated.

This is still a WIP.  We needed this at work so that we could install from
a readonly obj tree - lib32/build.sh wasn't up to that.

d18c990625 My take at improving the universe: allow the worlds to be
built in parallel.  Examples:

make universe
	Build worlds sequentially, each world sequentially.

make universe JFLAG=-j4
	Build worlds sequentially, each world in parallel.

make -j4 universe
make -j4 universe JFLAG=-j2
	Build four worlds in parallel, each world will be
	built in parallel too.  World parallelization is
	set to four in the first synopsis, and to two in
	the second.

make -j4 universe JFLAG=-B
	Build worlds in parallel, each world sequentially.

("world" == buildworld followed by buildkernels.)

0a9458250a As per discussions on current@, protect unsuspecting users from
trying to upgrade their system with make world instead of following
the preferred and suggested sequence of commands. The fact remains
that make world does not upgrade the kernel.
Allow make world when DESTDIR has been specified, including when
DESTDIR specifies the root file system. Otherwise, print a useful
warning and fail.

1a974787f9 Improvements on the 'make realclean' target. Some are style improvements,
but the biggest issue is that there are situatons when
${.OBJDIR} == ${.SRCDIR}, and in those situations the previous version
would happily remove all your /usr/src while it was cleaning out the objects.
Not that *you* would be happy about it...  Thanks to bde for immediately
noticing this serious possibility.

More improvements will be made to this target, but I wanted to commit this
safer version right now, before anyone lost their /usr/src due to it.

d911f786ab Limit testing for an up-to-date version of make(1) to the world and
buildworld targets by default, but allow it to be done for all user
targets by introducing a boolean option, named ALWAYS_CHECK_MAKE.

This change is by no means perfect and I don't even want to claim
this to be a solution. It does however address the fact that not
everybody likes to see make(1) rebuilt simply because the regression
test failed for some reason or other, including pilot error. It
therefore serves the purpose of keeping the crowd happy until we
have something better or simply reached a compromise.

The reasons for changing the default behaviour are:
o  It avoids a negative, possibly non-intuitive option,
o  It's according to POLA and fond of feet,
o  Only buildworld is documented to do its best to be
   successful at reasonably cost.
