r238211:
Support TARGET_ARCH=armv6 and TARGET_ARCH=armv6eb
This adds a new TARGET_ARCH for building on ARM
processors that support the ARMv6K multiprocessor
extensions. In particular, these processors have
better support for TLS and mutex operations.
This mostly touches a lot of Makefiles to extend
existing patterns for inferring CPUARCH from ARCH.
It also configures:
* GCC to default to arm1176jz-s
* GCC to predefine __FreeBSD_ARCH_armv6__
* gas to default to ARM_ARCH_V6K
* uname -p to return 'armv6'
* make so that MACHINE_ARCH defaults to 'armv6'
It also changes a number of headers to use
the compiler __ARM_ARCH_XXX__ macros to configure
processor-specific support routines.

This makes our naming scheme more closely match other systems and the
expectations of much third-party software. MIPS builds which are little-endian

When "make update" is run using a tree's makefile, it can also use
"cvs" (except for www/) and "svn" (only src/).
Clean up documentation and code regarding "make update":
- Increase oddness by adding support for WWWSUPFILE and NO_WWWUPDATE to
Makefile.inc1 (analogous to PORTSSUPFILE/NO_PORTSUPDATE and
DOCSUPFILE/NO_DOCUPDATE; WWWSUPFILE already supported by www/Makefile).
- Document all trees that support CVS_UPDATE.
- Document all trees that support SUP_UPDATE.
- Document SVN_UPDATE.
- Document NO_WWWUPDATE.
- make.conf(5) mistakenly said that *SUPFILE* had defaults.
- Add an example entry for WWWSUPFILE.
Some files keep the SUN4V tags as a code reference, for the future,
if any rewamped sun4v support wants to be added again.

Using the -mtime -0s (seconds, rather than no unit) avoids this 1s race.

Also add two new targets, packageworld and packagekernel, that tar up the
results of distributeworld and distributekernel (also new), respectively.
then that target is invoked for each architecture rather than the
default action of building world and kernels for each architecture.

need to do this because variables specified on the command line
override those specified in the Makefile. This is why we also moved
from TARGET to _TARGET in Makefile, and then set TARGET on the command
line when we fork a submake with Makefile.inc1.
This makes mips/mips work again, even without the workaround committed to
lib/libc/Makefile.
Properly document what `make targets` is supposed to list to avoid
further confusion given the place the target sits. Should have happened

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
TARGET_ARCH=y' since the latter are less tested.

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.
Added mips64e[lb] to make universe, so more kernels build.

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.

'make JFLAG=-j4 tinderbox' was equivalent to 'make -j4 universe'
(i.e. 4 worlds in parallel) rather than 'make JFLAG=-j4 universe'

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
