This produces a list of currently supported targets. Here "supported"
means "built in make universe" on the theory that those targets are
more supported than any that might work in 'make buildworld TARGET=x

Implement MACHINE_ARCH=mips64e[lb] to build N64 images. This replaces
MACHINE_ARCH=mipse[lb] TARGET_ABI=n64.
MACHINE_ARCH=mipsn32e[lb] has been added, but currently requires
WITHOUT_CDDL due to atomic issues in libzfs. I've not investigated
this much, but implemented this to preserve as much of the TARGET_ABI
functionality that I could. Since its presence doesn't affect the
working cases, I've kept it in for now.

not the one we build as part of make world. This means that make
universe will fail if building on a too-old current or any stable
system prior to a few days ago in weird ways (parse errors from
shell). This copes with these old systems in two ways:
(1) Works around the WARNING: issue by filtering all warnings that
sneak onto stdout.
(2) if TARGET_ARCH_${kernel} winds up being empty, then we error out
immediately with a semi-useful error message. This usually comes from
config not groking -m.
Ideally, we'd use a buildworld's config here, but that's tricky, so
I'll leave that detail to others to fix (it has to be done post make
world for the arch rather than at the top level makefile). This
should make 'make universe' usable from recent 8-stable systems
(recent == last few months or so) for building -current. They have
-m, but spewed warnings out stdout. Older systems will now at least
get a firm error early rather than a confusing error late.

TARGET_BIG_ENDIAN is now completely dead, except where it was
originally supposed to be used (internally in the toolchain building).
TARGET_ARCH has changed in three cases:
(1) Little endian mips has changed to mipsel.
(2) Big endian mips has changed to mipseb.
(3) Big endian arm has changed to armeb.
Some additional changes are needed to make 'make universe' work on arm
and mips after this change, so those are commented out for now.
UPDATING information will be forthcoming. Any remaining rough edges
will be hammered out in -current.

Now that we use C99 almost everywhere, just use C99-style in the pmap

it from cdefs.h as well. Because the flag was only introduced 17 months
ago, I don't expect any problems.

universe target slightly more useful in cases the universe is limited
to a developer's scope or objectives. For example, when a universe
failed for a particular platform and fixes need to be tested for that
particular platform then a developer can restart the universe for
only that platform, even if the initial universe is still building

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

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.
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.
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.

therefore serves the purpose of keeping the crowd happy until we

o Only buildworld is documented to do its best to be
