12a14de08e MFP4 change 214967:
Make the process of embedding MDROOT images less perilous by
	makeing the target that links kernel and embedding the image
	depend on the image.  This means, if the image doesn't exist you
	find out before you try to boot from it and that if you change
	the image you don't have to touch some random source file to
	cause a rebuild.

	Don't hide that we're embedding the image.

1e8e2a9d7d Unfortunately the change in r237958 resulted in s/install/instclean/ due to
the aggressive pattern matching of the :C modifier. I tested build and
install in 2 phases, however with different solutions, resulting in the
breakage. Mea culpa.

The solution is to break out the all: target. This causes a few lines of
code duplication, but now the all: target works as it should, and the
other targets continue to work as they did before.

While I'm here, add a ===> header line to the start of each port build
to make it easier to find/more clear in the logs.

cea039dae1 For the ports modules building code, clean WRKDIR before building. This is
important for those that use -DNO_CLEAN routinely, since it will prevent
installing stale stuff, and even more important when the port is upgraded
to a newer version. When the user doesn't use -DNO_CLEAN, this will create
an infinitesimal amount of extra work, but won't hurt anything.

This is necessary because the ports tree has flags that prevent the ususal
'update the build if newer source files exist' logic from doing what it
would do in the base.

LOCALBASE/bin and sbin to PATH, allowing dependencies to be found;
adding SRC_BASE and OSVERSION to match the new kernel, and putting
the related builds under MAKEOBJDIRPREFIX so that they only need
to be built once per kernel.

88c7c4348b Allow (with a license warning) "options ZFS" to work in static kernels.
The 'make depend' rules have to use custom -I paths for the special compat
includes for the opensolaris/zfs headers.

This option will pull in the couple of files that are shared with dtrace,
but they appear to correctly use the MODULE_VERSION/MODULE_DEPEND rules
so loader should do the right thing, as should kldload.

78e7e3ecb5 - fix WITH_CTF when specified in /etc/src.conf [1]
- CTFCONVERT_CMD=... is a hack (should be defined to empty string instead):
make(1) should be taught to ignore empty commands silently in compat mode
(as it does in !compat mode, GNU make also silently ignores empty commands)
and to skip printing empty commands in !compat mode
- config(8) should generate ${NORMAL_CTFCONVERT} invocation without '@':
this will allow to simplify kern.pre.mk even more and lessen the number
of shell invocations during kernel build when CTF is turned off
- WITH_CTF can now be converted to usual MK_CTF=yes/no infrastructure

to amd64, i386, and pc98.  The headers are installed to /usr/include/x86

similar to 'machine' so that the headers can be included as <x86/foo.h>.

21edb039c6 WITH_CTF can now be specified in src.conf (not recommended, there
are some problems with static executables), make.conf (would also
affect ports which do not use GNU make and do not override the
compile targets) or in the kernel config (via "makeoptions
WITH_CTF=yes").

Additional (related) changes:
 - propagate WITH_CTF to module builds
 - do not add -g to the linker flags, it's a noop there anyway
   (at least according to the man page of ld)
 - do not add -g to CFLAGS unconditionally
   we need to have a look if it is really needed (IMO not) or if there
   is a way to add it only when WITH_CTF is used

Note: ctfconvert / ctfmerge lines will not appear in the build output,
to protect the innocent (those which do not build with WITH_CTF would
see the shell-test and may think WITH_CTF is used).

to module builds.  This avoids having to have the module builds walk up
the tree to find the kernel sources.  It also allows a kernel + module
build to succeed when a new level of module subdirectories is added without
requiring that the /usr/share/mk/bsd.kmod.mk file on the machine be patched.

98b45a8ff8 Installing debug modules was a bad idea -- I bogusly assumed that

d24864f785 Refactor (some more) installation of kernel and module objects.
Try to make everyone happy: David (to have debug kernels installed
by default), Warner (to be able to override that), and myself (for
actually making it all work and to be consistent).

Now, if kernel was configured for debugging (through DEBUG=-g in
the kernel config file or "config -g"), doing "make install" will
install debug versions of kernel and module objects with their
canonical names,

	kernel.debug -> /boot/kernel/kernel
	if_fxp.ko.debug -> /boot/kernel/if_fxp.ko

Installing a kernel not configured for debugging, or debug kernel
with INSTALL_NODEBUG variable defined, will install non-debug
kernel and module objects.

Also, restore the install.debug and reinstall.debug targets that
are part of the existing API (they cause some additional gdb(1)
scripts to be installed).

697ca17bb0 Back out most of 1.84. It was unwise to force debug kernels to always
be installed.  It should have been optional to install a non-debug
one, just like it was formerly optional to install a debug one.  In
order to do that, most of 1.84 had to go.

Instead, make installing the debug kernel the default, but create a
new option INSTALL_NODEBUG for those people that have small /
partitions and good source control habits.

This preserves the behavior of 1.84 while allowing it to be overriden
for people (like me) that do not have the time to upgrade to get a
bigger / and also don't have time for stupid makefile tricks when
upgrading their older system, but still want a kernel.debug around if
things go south.
