b2d840b61f 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.

8cd489b218 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).

c87b25b2ae 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.

1ba5532df7 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.

more in the projects/ifnet. Moving out of contrib also allows to remove

007999d737 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.

f17cb55447 Introduce a new make variable COMPILER_TYPE that specifies what
type of compiler is being used (currently clang or gcc).  COMPILER_TYPE
is set in the new bsd.compiler.mk file based on the value of the CC
variable or, should it prove informative, by running ${CC} --version
and examining the output.

To avoid negative performance impacts in the default case and correct
value for COMPILER_TYPE type is determined and passed in the environment
of submake instances while building world.

Replace adhoc attempts at determining the compiler type by examining
CC or MK_CLANG_IS_CC with checks of COMPILER_TYPE.  This eliminates
bootstrapping complications when first setting WITH_CLANG_IS_CC.
