I got annoyed by the number of warnings that the CheriBSD build was
emitting. It turns out that we are emitting lots of warnings during
bootstrap because bootstrap tools are built with the default compiler
flags and ignore the warnings flags that are set in bsd.sys.mk.
Looking at git blame, it appears that MK_WARNS=no has been passed since
rS112869, replacing the -DNO_WERROR option that was added in rS87775.
This commit changes MK_WARNS=no back to -DNO_WERROR. We need to pass
-DNO_WERROR, since the system compiler might have new warnings that we
don't know about yet, and we shouldn't fail the build in that case.

Only keep the widechar version of ncurses as libncursesw.so.9
Keep the old name to avoid breaking the ABI compatibility (the non
widechar version libncurses.so.9 is not binary compatible with
libncursesw.so.9) since all ports and base are already only linking
against the widechar version we can simply remove libncurses.so.9
Since the .9 version only lived in the dev branch and never ended in a
release, it is simply removed and not added to any binary compat
package.
Add symlinks to keep build time compatibility for anyone linking against
-lncurses
This allows use of the standard src.conf configuration for controlling
whether the tree is cleaned before build or not. The default is still
to clean.
Setting either NOCLEAN or NO_CLEAN will mention the new src.conf option.
NOCLEAN remains a .warning, while for now NO_CLEAN is .info.

When building on non-FreeBSD systems we need to pass an explicit target
triple to clang otherwise it will attempt to build with the host triple.
This also has advantages when building on a FreeBSD host: we now tell
clang that we are targeting at least FreeBSD 12.0 instead of an older
version so it can enable newer features.

The lib32 build was already building the i386 version of
the clang sanitizers (libclang_rt) but they were not being
installed. This enables the installation.
MK_TOOLCHAIN=no was originally added to the install make
environment to disable includes so that NO_INCS could be
removed. The MK_TOOLCHAIN in bsd.incs.mk was subsequently
renamed to MK_INCLUDES, but bsd.lib.mk doesn't even include
bsd.incs.mk when LIBRARIES_ONLY is defined which the install
make environment for compat libs now defines. However,
setting MK_TOOLCHAIN=no forced MK_CLANG=no which disabled
libclang_rt during the install32 phase. Remove MK_TOOLCHAIN=no
since LIBRARIES_ONLY is now sufficient.
Since the libcompat environment overrides both LIBDIR and
SHLIBDIR, libclang_rt/Makefile.inc has to set both variables
to force the libraries to be installed to the location
expected by the compiler.

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 could happen with either WITHOUT_AUTO_OBJ=yes or MAKELEVEL>0 for
the initial 'make buildworld' command.
This now ensures that build-tools targets have 'make obj' ran if needed.
This is especially problematic for pmu-events since it is not directly
connected in the build. Normally the 'make includes' call right before
this implicitly creates the objdir with a 'make obj' already but
misses pmu-events because it is disconnected from lib/libpmc. Fixing that
would make this new 'make obj' pointless but it is being added to avoid
this problem in the future should another tool be connected like this.

This problem was caused by r325329 and r325350.
For the release(7) targets, some will run mm-mtree.sh which itself runs make
with a MAKEOBJDIRPREFIX. The execution of that script leaks OBJROOT,
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
as r325329 is doing, then the wrong OBJDIRs end up being used due to the
unemptied MAKEOBJDIRPREFIX being preferred over the proper MAKEOBJDIR.

native builds, and /usr/obj/<target>.<target_arch>/<srcdir> for cross builds to
a new simpler format of /usr/obj/<srcdir>/<target>.<target_arch>. This
new format is used regardless of cross or native build. It allows
easier management of multiple source tree object directories.

In a cross-build, the build-tools are native host binaries. We do not
want to rebuild them when building for the target. Bmake previously
did not support checking .NOMETA on an existing target, so .NOMETA_CMP
was used here. However, .NOMETA_CMP still triggers meta mode conditions
if the number of commands or the command changes. In r312467 the paths
to build ncurses files were modified and thus triggered meta mode to
rebuild the build tools (make_keys, make_hash) in ncurses during the
target build. Bmake 20160604 committed in r301462 changed .NOMETA to
also skip meta mode logic for an existing .meta file as well, thus it
is now the proper fix here.
I explored moving the build-tools output to WORLDTMP/tools with
relatively good success, but have concerns that doing so would be
problematic for downstream vendors who use LOCAL_TOOL_DIRS and
expect the tools to be in current OBJDIR for the target. It also
adds more complexity into finding the tools during target build
and handling of where they are for rescue/rescue and
mkcsmapper_static/mkesdb_static which should really not be connected in
build-tools anyway.

There were a few issues.
- In-tree GCC won't have X_COMPILER_TYPE defined but will have
WANT_COMPILER_TYPE==gcc set from the SYSTEM_COMPILER logic that can
be used. Make the clang check specific to clang as well to ensure
-target doesn't leak into a GCC build.
- When using a cross-compiler GCC (with a default sysroot or arch) and also
passing --sysroot, it basically forgets all internal paths for
libraries. We've already worked around this quite a bit for
the external toolchains. Now for the in-tree bootstrap cross-compiler
GCC, also pass in the needed -B${WORLDTMP}/usr/lib to find the crt
object files, but also -isystem and -L to fix the paths. This creates
quite a spammy build log, but it is clear and still achieves the goals
and stays consistent between internal and external build flags.
Reducing the spam by using the '=' prefix feature will help and be
done later.
