r335653 flipped the order in which hints/env files are concatenated to match
the order in which vars are processed by the kernel. This is the other
hammer to drop.
Use nv(9) to de-dupe entries within a single `hint` or `env` file, using the
latest value specified for a key. This leaves some duplicates if a variable
is specified in multiple hint/env files or via `envvar` in a kernel config,
but the reversed order of concatenation (from r335653) makes this a
non-issue as the latest-specified version will be seen first.
This change also silently rewrote hint bits to use the same sanitization
process that ian@ wrote for r335642. To the kernel, hints and env vars are
basically the same thing through early boot, then get merged into the
dynamic environment once kmem becomes available and the dynamic environment
is created. They should be subjected to the same restrictions.
libnv has been added to -legacy for the time being to support the build of
config(8) with the new cnvlist API.

Currently the mtree calls in Makefile.inc1 all change the directory owner
to match the spec file. However, we should not be doing this during
distributeworld if -DNO_ROOT is passed. Additionally, when creating the
WORLDTMP directory hierachy there is no need to change the owner to root so
we now always pass the -W flag when populating WORLDTMP.
This is also required for building FreeBSD on Linux/Mac since the required
groups/users will not exist there which is how I discovered this issue.

This works similar to WITH_SYSTEM_COMPILER added in r300354. It only
supports lld via WITH_LLD_BOOTSTRAP.
When both SYSTEM_COMPILER and SYSTEM_LINKER logic passes then libclang
will not build in cross-tools. If either check fails though then
libclang is built.
The .info is reworked to notify when libclang will be built since if
either clang or lld needs to be rebuilt, but not the other, the
notification can lead to confusion on why "clang is building".
-fuse-ld= is not used with this method so some combinations of compiler
and linker are expected to fail.
A new 'make test-system-linker' target is added to see the logic results.
Makefile.inc1:
CROSS_BINUTILS_PREFIX support had to be moved higher up so that XLD
could be set and MK_LLD_BOOTSTRAP disabled before checking SYSTEM_LINKER
logic as done with SYSTEM_COMPILER. This also required moving where
bsd.linker.mk was read since XLD needs to be set before parsing it. This
creates a situation where src.opts.mk can not test LINKER_FEATURES or
add LLD_BOOTSTAP to BROKEN_OPTIONS.

9.3 is the final 9.x release and does not contain the r286035 fix.
10.3 is the first 10.x release with the fix. Thus, in practice 10.3 is
the oldest release that can build HEAD.
Although it may still be possible to build HEAD from an up-to-date

This problem was caused by r325329 and r325350.
For the release(7) targets, some will run mm-mtree.sh which itself runs make

MAKEOBJDIR, and MAKELEVEL=1 in the environment. This causes the mm-mtree makes
to not do some basic setup of OBJROOT and only use this special
MAKEOBJDIRPREFIX case which fails to empty out MAKEOBJDIRPREFIX for further
nested makes, such as a tree walk. If that tree walk sets OBJROOT/OBJTOP such

This takes longer but should reliably produce working binaries.
The old version linked against system libraries and headers
which would be a problem if building a native-xtools against
a newer source than the host system. With a proper sysroot made
first this is not a problem.
This also allows:
- NXBDIRS to be built in parallel
- NXBDIRS to be installed to NXBDESTDIR in parallel
- SYSTEM_COMPILER logic to work again. Note that because this change
is adding a sysroot phase the compiler may be built up to twice now.
The first is the "cross-compiler" even though it is for the native
architecture, but it is still built to ensure the latest compiler
is used to generate the binaries, unless SYSTEM_COMPILER allows
/usr/bin/cc to be used. Then the target compiler is built
which is actually a cross-compiler since it runs on native host
but generates TARGET.TARGET_ARCH binaries.
Note this also changes the path used for the OBJDIR. It used to use
/usr/obj/target.target_arch/nxb/<srcdir> for objects and
/usr/obj/target.target_arch/nxb-bin for installed files, but now uses
/usr/obj/nxb/target.target_arch/<srcdir> for objects and
/usr/obj/nxb/target.target_arch/<srcdir>/nxb-bin for installed files.
- NXBDESTDIR can be specified for where to install or queried with
`make -f Makefile.inc1 TARGET=... TARGET_ARCH=... -V NXBDESTDIR`
This could potentially be improved to reuse an existing sysroot. The
problem is with building the SUBDIR_OVERRIDE list it needs to use a
different OBJDIR since it is building all statically. We don't want to
pollute the existing 'buildworld' OBJDIR and cause confusion on the next
build. Using a separate OBJDIR for the 'everything' phase mostly works
except for some things like linking in INTERNALLIBS that exist in the
other OBJDIR.

Make armv7 as a new MACHINE_ARCH.
Copy all the places we do armv6 and add armv7 as basically an
alias. clang appears to generate code for armv7 by default. armv7 hard
float isn't supported by the the in-tree gcc, so it hasn't been
updated to have a new default.
Support armv7 as a new valid MACHINE_ARCH (and by extension
TARGET_ARCH).
Add armv7 to the universe build.

LLD_BOOTSTRAP is intended to control the linker used to link world and
kernel, while LLD_IS_LD is intended to control the linker installed in
that world.
Force LLD_IS_LD equal to LLD_BOOTSTRAP for the cross-tools build and
install phase, so that lld will be installed as the ld to run on the
host, when LLD_BOOTSTRAP is set.

Disconnect the dependency on the kernel package from the runtime
package. There are a number of problems here:
1) The runtime package installed into a chroot or a jail would
include the kernel package, changing the behavior of how jails
work now [1];
2) As result of (1), it is possible a binary may incorrectly
resolve kernel symbols [2]; in addition, it is possible there
will be unexpected fallout with 32-bit jails on a 64-bit host
kernel [2].

Instead of traversing src/sys, as is done by newvers.sh for uname(1),
a full tree walk is done to prevent userland and/or modifications
from not being reflected in a modified tree (M).

The idea here is that, provided upstream pkg(8) maintainers accept
the proposed change, the kernel.ucl will contain a post-install
script causing pkg(8) to emit a message informing to reboot the
system after the kernel is upgraded using 'pkg upgrade', so the
new userland is installed on the running new kernel. At present,
this functionality does not exist in pkg(8), but will help ensure
the upgrade path follows that from UPDATING. To work around this
for now, evaluate ASSUME_ALWAYS_YES, and prompt the user if they
wish to proceed if not set to true.
Since there is a kernel dependency, and a non-GENERIC kernel may
be in use, update Makefile.inc1 to replace '%KERNCONF%' in the
runtime.ucl with the first-built kernel set either via command line
or in make.conf(5).

- bsd.compiler.mk: Must ensure that the CCACHE_WRAPPER_PATH comes first
in PATH.
- Makefile.inc1: Must prepend the CCACHE_WRAPPER_PATH into BPATH as it
overrides the PATH set in bsd.compiler.mk in sub-makes. The PATH
set in bsd.compiler.mk is not exported and doing so would cause it to
then override the BPATH set from environment. The only sane solution
is to prepend into BPATH as needed.
CCACHE_PATH could possibly be used for some of this as well.

Since we imported clang 5.0.0, the version check in Makefile.inc1 which
checks whether to use libc++ fires even when the compiler for the target
architecture is gcc 4.2.1. This is because only X_COMPILER_VERSION is
checked. Also check X_COMPILER_TYPE, so it will only use libc++ when an
external gcc toolchain is used.

It is full of distracting noise about UPDATING and may confuse

possible to have directories removed on every run with
use of WITHOUT_ knobs that the mtree files do not

in OLD_DIRS currently.

In a scenario of cross-building it is possible that an OBJDIR's WORLDTMP
contains an older compiler in WORLDTMP/usr/bin/cc that is not rebuilt
if SYSTEM_COMPILER logic is triggered. This compiler was still
incorrectly used. Address this by removing WORLDTMP/usr/bin/cc and all
of the hardlinked files associated with it. Also do this for c++ for
GCC builds.
