This Makefile sets KERN_OPTS. This permits kernel module Makefiles to
use KERN_OPTS to control the value of variables such as SRCS that are
used by bsd.kmod.mk for KERN_OPTS values that honor WITH/WITHOUT
options for standalone builds.
Each boot, regenerate /var/run/os-release based on the currently running
system. Create a /etc/os-release symlink pointing to this file (so that this
doesn't create a new reason /etc can not be mounted read-only).
This is compatible with what other systems do and is what the sysutil/os-release
port attempted to do, but in an incomplete way. Linux, Solaris and DragonFly all
implement this natively as well. The complete standard can be found at
https://www.freedesktop.org/software/systemd/man/os-release.html
Moving this to the base solves both the non-standard location problem with the
port, as well as the lack of update of this file on system update.

Mount the UEFI ESP on /boot/efi. No current system uses this by default, but
there are many ad-hoc schemes that do this in /efi or /esp or /uefi and adding a
new directory at the top-level would have a much higher likelihood of
collision. Document this in /etc/mtree/BSD.root.mtree and create EFIDIR and
related variables in bsd.own.mk.

As of FreeBSD 10.1 the autofs(5) is available for automounting, and the
amd man page has indicated that the in-tree copy of amd is obsolete.
Disable it by default for now, with the expectation that it will be
removed before FreeBSD 13.0.

FreeBSDlua ("flua") is a FreeBSD-private lua, flavored with whatever
extensions we need for base system operations. We currently support a subset
of lfs and lposix that are used in the rewrite of makesyscall.sh into lua,
added in r354786.
flua is intentionally written such that one can install standard lua and
some set of lua modules from ports and achieve the same effect.
linit_flua is a copy of linit.c from contrib/lua with lfs and lposix added
in. This is similar to what we do in stand/. linit.c has been renamed to
make it clear that this has flua-specific bits.
luaconf has been slightly obfuscated to make extensions more difficult. Part
of the problem is that flua is already hard enough to use as a bootstrap
tool because it's not in PATH- attempting to do extension loading would
require a special bootstrap version of flua with paths changed to protect
the innocent.
src.lua.mk has been added to make it easy for in-tree stuff to find flua,
whether it's bootstrap-flua or relying on PATH frobbing by Makefile.inc1.

By using '__' instead of '.' as the separator we can also support systems
that use dash as /bin/sh (it's the default shell on Ubuntu/Debian). Dash
will unset any environment variables that use a non alphanumeric+undedscore
character and therefore submakes will fail to import the COMPILER_*
variables if we use '.' as the separator.

Disable the use of executable 2M page mappings in EPT-format page
tables on affected CPUs. For bhyve virtual machines, this effectively
disables all use of superpage mappings on affected CPUs. The
vm.pmap.allow_2m_x_ept sysctl can be set to override the default and
enable mappings on affected CPUs.
Alternate approaches have been suggested, but at present we do not
believe the complexity is warranted for typical bhyve's use cases.

Don't depend on CPUTYPE to define powerpcspe CFLAGS, they should be set
unconditionally. This reduces duplication. Also, set some CFLAGS as
gcc-only, because clang's SPE support always uses the SPE ABI, it's not an
optional feature.
Previously ntb_transport(4) required at least 6 scratchpad registers,
plus 2 more for each additional memory window. That is too much for some
configurations, where several drivers have to share resources of the same
NTB hardware. This patch introduces new compact version of the protocol,
requiring only 3 scratchpad registers, plus one more for each additional
memory window. The optimization is based on fact that neither of version,
number of windows or number of queue pairs really need more then one byte
each, and window sizes of 4GB are not very useful now. The new protocol
is activated automatically when the configuration is low on scratchpad
registers, or it can be activated explicitly with loader tunable.

Address Lookup Table (A-LUT) being enabled allows to specify separate
translation for each 1/128th or 1/256th of the BAR2. Previously it was
used only to limit effective window size by blocking access through some
of A-LUT elements. This change allows A-LUT elements to also point
different memory locations, providing to upper layers several (up to 128)
independent memory windows. A-LUT hardware allows even more flexible
configurations than this, but NTB KPI have no way to manage that now.

We will soon remove the BSD_CRTBEGIN option (and will use the new CRT
files always) as part of the GCC 4.2.1 removal. Right now BSD_CRTBEGIN
works everywhere but sparc64; add a reference to the PR in case anyone
stumbles across this and is looking for more information.
The man page incorrectly described the use of the"len" argument, which
is updated to the number of bytes copied and not reduced by the number
of bytes copied.
This is a content change.

Alter bsd.compat.mk to set MACHINE and MACHINE_ARCH when included
directly so MD paths in Makefiles work. In the process centralize
setting them in LIBCOMPATWMAKEENV.
Alter .PATH and CFLAGS settings in work when the Makefile is included.
While here only support LIB32 on supported platforms rather than always
enabling it and requiring users of MK_LIB32 to filter based

The net effect of this change is to make Makefile.libcompat only build

Changes relative to r354449:
Correct detection of the compiler type when bsd.compat.mk is used
outside Makefile.libcompat. Previously it always matched the clang
case.
Set LDFLAGS including the linker emulation for mips where -m32 seems to
