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.
Remove __gnu89_inline.
Now that we use C99 almost everywhere, just use C99-style in the pmap
code. Since the pmap code is the only consumer of __gnu89_inline, remove
it from cdefs.h as well. Because the flag was only introduced 17 months
ago, I don't expect any problems.

It was backed out, because it prevented us from building kernels using a
7.x compiler. Now that most people use 8.x, there is nothing that holds
us back. Even if people run 7.x, they should be able to build a kernel
if they run `make kernel-toolchain' or `make buildworld' first.
make universe, split the logic into two parts:
- 1st to build worlds and generate kernel configs like LINT.
- 2nd to build kernels for a given TARGET architecture correctly
finding all newly generated configs, not knowing anything about
LINT anymore. (*)
(*) If you know better/cleaner/... ways to do this, let me know.

you can build the cross development tools and install them as
$XDEV-freebsd-xxx for each tool. This allows one to use autoconf to
find the tools for cross building scenarios.
`make universe'. This catches a few more arm and, once enabled, mips
configs and permits having local configs named like NOINET6.

a developer can rest reasonably assured that the tinderbox will not
be broken. This target leverages most of 'universe' but will exit
non-zero and output a summary at the end.

no active development on it for over a year now and it isn't
reliable under a simple buildworld. Developers can't be expected to
test code targeted for it.

src/Makefile has in abudnance.
and that controls which platforms are being built as part of a "make
universe". By default TARGETS is set to the 8 platforms currently
being built. This variable is useful for running or re-running a
"make universe" with only a selected set of platforms. This makes the
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
other platforms.
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.

- 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

Approved by: mentor (joerg)
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.
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.
