This adds some support for ARM as well as 64-bit. 64-bit on PowerPC is
currently not working, and ARM support has not been completed or tested on the
FreeBSD side.
As this was imported from a Linux tree, it includes some Linux-isms
(ioread/iowrite), so compile with the LinuxKPI for now. This may change in the
future.
We must send either an IDLE IMMEDIATE or a STANDBY IMMEDIATE to drives
on warm boot so their SMART and other volatile data is
persisted. However, for a warm boot we don't want to send STANDBY
IMMEDIATE to some spinning drives because they will spin down. If
there's a lot of these drives on the system, that can cause a
thundering herd problem at startup time (that in extreme cases causes
timeout in device discovery).

make buildenv BUILDENV_SHELL=<some command> more useful. Remove '||
true' from the command line so that errors are properly
returned. There appears to be no reason for it, and it dates back to
the original commit by ru@.

To ensure that I don't break the MK_ZFS=no case (currently working),
add that to the build, at least for i386 and amd64. Also, out of an
abundance of caution, clean single threaded, and then build in a
separate make. Otherwise, I hit a race where we build before objdir
has been created, which breaks at the moment.

Use defines from defs.mk in most MD code (the biggest exception is
x86, which will be its own commit due to its size). Prefer including
bsd.init.mk over the variations (../Makefile.inc and src.opts.mk being
the two biggest ones).

timer frequency a power of two. This changes the frequency from 10 to
16.7 MHz (2 ^ 24 HZ). Using a power of two avoids roundoff errors when
doing arithmetic in sbintime_t units.
Testing shows this can fix erratic ntpd behavior in guests using the
hpet timer (which is the default for multicore guests).

- Remove FreeBSD 4.x of building the kernel.
While it might technically work, it is better to
document the 'correct' way than how to shoot oneself
in the foot
- Remove reference to CVS -P for src.
Define EFISRC, EFIINC and EFIINCMD. Use them, as well as using other
symbols defined in defs.mk. Prefer <bsd.init.mk> to ../../Makefile.inc
or <src.opts.mk>.

It is possible that building headers requires an OBJDIR.
The other phases of xdev have their own 'make obj' calls
where needed, such as inside 'make libraries' itself.

Having objects in world32 and a sysroot in lib32 was confusing and
inconsistent with the normal build. Now objects are stored in
obj-lib32 (or obj-libsoft) and the sysroot (analagous to WORLDTMP)
is stored in obj-lib32/tmp.

Without this the user has to mess with 'make -f Makefile.inc1 ...' to figure
out where the files are installed in the OBJDIR and then they need to copy them
to where they really wanted them. Using DESTDIR may be problematic after
r325001 as well.
The files will be installed to DESTDIR/NXTP where NXTP defaults to /nxb-bin.

The top of Makefile.inc1 requires TARGET/TARGET_ARCH be defined. Just
building 'make xdev' would already set them, so this error was never
triggered. Moving it to Makefile fixes the problem.

The original change was dealing with the build wanting to run a newer
install(1) that was not yet installed. The solution to look into the private
legacy directory of the existing build conflicts with 2 upcoming features: a
changed OBJDIR format, and splitting the host tools into arch-dependent and
arch-independent directories. Rather than hardcoding and changing the paths in
this script, just let kernel-toolchain do the work, while disabling much of the
meat. With -j15 this finishes in 25 seconds for me and 117 seconds with -j1.
All that is really needed is bootstrap-tools, but the system is not currently
written in a way that all previous dependent steps will have ran. The previous
steps, such as _worldtmp, are being reworked and renamed and so cannot be
relied upon to be right.

Its own build target was already handling mtree extractions
just as _worldtmp did, so the other cleaning of the
tmpdir makes sense here as well.

Only remove them if the option is enabled and also handle libsoft
by using the proper LIBCOMPAT_OBJTREE. LIBCOMPAT:D will expand
the text after it as a proper glob to the command line if LIBCOMPAT
is defined.

The _worldtmp target is for setting up WORLDTMP. Nothing between _worldtmp
and _cleanobj will read these files. Move to its own target since it is
so large.

This leaks into the PATH handling for WORLDTMP and breaks
finding cross-tools. The PATH handling could be fixed to
properly quote but is not worth the effort.
Also allow this sanity check to always run even with 'make -n'.
