88fe1f7ab3 Add guessed dependencies to OBJS after bsd.dep.mk in case of it adding to SRCS.
This was a regression in r295985.

bsd.dep.mk adds to SRCS for dtrace probes, yacc grammars and some
others.

The code that is moving is planned to be removed once FAST_DEPEND is
default (and the only option) though since FAST_DEPEND doesn't use this.

d7beff082b FAST_DEPEND: Rework how guessed dependencies are handled.
Rather than depend on .depend not existing, check the actual
.depend.OBJ file that will be used for that object.  If it doesn't
exist then use the guessed dependencies.

FAST_DEPEND may never have a .depend file.  Not having one means all of the
previous logic would over-depend all object files on all headers which is not
what we wanted.  It also means that if a .depend is generated before a build
is done for _EXTRADEPEND (such as for PROG or LIB) then all of these
dependencies would not be used since the .depend wasn't generated from mkdep
and the real .depend.* files are not generated until the build.

68d969232c kmod.mk: Ensure ILINKS are created before building.
This allows skipping 'make depend' or running 'make clean all' without
getting a flip-flopping dependency due to the exists() just below.
Otherwise an error is encountered, such as:
  fatal error: 'machine/endian.h' file not found.

8598392cd1 Build changes that allow the modules on arm64.
- Move the required kernel compiler flags from Makefile.arm64 to kern.mk.
- Build arm64 modules as PIC; non-PIC relocations in .o for shared object
  output cannot be handled.
- Do not try to install aarch64 symlink.
- A hack for arm64 to avoid ld -r stage.  See the comment for the explanation.
  Some functionality is lost, like ctf handling, but hopefully will be
  restored after newer linker is available.

05117b57a5 Install kernel debug data under /usr/lib/debug
This avoids needing a large boot partition / file system in order to
accommodate multiple kernels, and provides consistency with userland
debug. This also simplifies the process of moving kernel debug files
to a separate package and installing them on demand.

In addition, change kernel debug file extension to .debug, to match
userland debug files.

When using the supported kernel installation method the
/usr/lib/debug/boot/kernel directory will be renamed (to kernel.old)
as is done with /boot/kernel.

Developers wishing to maintain the historical behavior of installing
debug files in /boot/kernel/ can set KERN_DEBUGDIR="" in src.conf(5).

12f05b8446 Kill MFILES and find things automatically. It turned out to be only
lightly used. Find the proper .m file when we depend on *_if.[ch] in
the srcs line, with seat-belts for false positive matches.  This uses
make's path mechanism. A further refinement would be to calculate this
once, and then pass the resulting _MPATH to modules submakes.

7dd824c370 Fix kernel build ${MACHINE} path
$M should be the kernel machine src directory, ${MACHINE}. In most cases
${MACHINE} and ${MACHINE_CPUARCH} are the same, but this is not true for
pc98 and arm64.

It appears we previously set M=${MACHINE_CPUARCH} as a workaround to
accommodate pc98, where MACHINE_CPUARCH is pc98 but it uses
sys/i386/i386/genassym.c.

arm64 relies on this being set correctly, so update $M and add explicit
workarounds for pc98.

discontinued by its initial authors. In FreeBSD the code was already
slightly edited during the pf(4) SMP project. It is about to be edited
more in the projects/ifnet. Moving out of contrib also allows to remove
several hacks to the make glue.

KERNBUILDDIR. Come up with some sensible defaults (though listing them
in kmod.mk may be unwise -- we have no easy way to know what are the
best sensible defaults for everything so we just catch the big stuff).
Append SRCS.${opt} for each option in KERN_OPTS to SRCS to allow easy
conditional compilation. Append any notion of KERN_OPTS_EXTRA to the
list of kernel opts.

b54c389fbc Put in a workaround for bug 196407 (arm modules cause crashes & panics).
When we started compiling the kernel with -march=armv7 the compiler
started emitting new types of relocation info which are incompatible with
the shared-lib file format used by .ko modules.  This workaround prevents
the compiler from emitting the instruction sequences that require the
new relocs.  This amounts to using an undocumented internal compiler
flag, so this is just a temporary workaround while we look for a good fix.
