While *most* projects need only DEP_MACHINE for host, there is always
an exception. So we allow for TARGET_SPEC_VARS.host to be a subset of
TARGET_SPEC_VARS. The default will *just work* for most projects.
We set DEP_TARGET_SPEC_VARS and hence DEP_TARGET_SPEC based on
DEP_MACHINE. Allow for M_dep_qual_fixes.host to be different too and
take care to apply the right set.
Add more comments to explain what and why.
Ensure OBJROOT ends in / or - (/ preferred).
Export OBJTOP if level > 0
this avoids the issue with bmake/unit-tests.
Check if we have to override MAKEOBJDIR
and if so, put it into env correctly.
Rather than define the TARGETS and TARGET_ARCHES in src/Makefile
put them in sys.machine.mk so they can also be leveraged by
non-top-level builds.
We have TARGET_MACHINE_LIST as the list of MACHINES we build for.
For each MACHINE we have a MACHINE_ARCH_LIST_${MACHINE}
and the first entry of each list is used as default for
MACHINE_ARCH_${MACHINE}
We can now remove a bunch of MACHINE_ARCH.* handling from
local.sys.dirdeps*mk

When originally implemented, there was no distinction between
DIRDEPS_BUILD and META_MODE, they were one and the same.
META_MODE however is useful by itself, but since meta.sys.mk
had lots of settings related to DIRDEPS_BUILD its use was limited
to DIRDEPS_BUILD.
Move (most) DIRDEPS_BUILD related items to sys.dirdeps.mk
so that meta.sys.mk can be used for just META_MODE.
There is of course some bluring of the lines, so settings remain
in meta.sys.mk
Add MK_META_ERROR_TARGET to enable the META_MODE .ERROR target
independent of DIRDEPS_BUILD, it copies failed .meta files to ${SB}/error
to make it easier to identify the cause of build failures.
Since sys.dirdeps.mk should be included first, most of
local.meta.sys.mk becomes local.sys.dirdeps.mk
and some other bits need to move to local.sys.dirdeps.env.mk
Also fix dirdeps.mk to not add CURDIR to DIRDEPS when it is SRCTOP.

Latest meta.sys.mk follows sys.mk in including local.meta.sys.env.mk
and local.meta.sys.mk late, but we have things we need done early
so move them to local.meta.sys.env.mk
The whole point of the DIRDEPS_BUILD is to avoid tree walks
and basically build everything in a single pass.
We use the pseudo MACHINE "host" to represent the build host.
When the build host is not FreeBSD or is an older version of FreeBSD
it may need some help to build host-tools.
The directory tools/build does this - building libegacy.
local.sys.mk: create a pseudo option MK_host_egacy to indicate
if tools/build needs to be built for "host".
local.dirdeps.mk: set MK_host_egacy.host to ${MK_host_egacy}
all other DEP_MACHINES will get "no"
This allows a Makefile.depend.options in makefs etc to cause tools/build
to be built for host but only if necessary.
local.init.mk: use ISYSTEM as arg to -isystem so that it can be overridden.
The default remains ${STAGE_INCLUDEDIR}
src.init.mk: if MACHINE is host and we are not FreeBSD
set some MK_ flags the same as tools/build/mk/Makefile.boot.pre and
include src.init.${.MAKE.OS:tl}.mk if it exists.
For older versions of FreeBSD add libegacy when building PROGs for "host"
Also instead of -isystem${STAGE_INCLUDEDIR} we want
-I${STAGE_INCLUDEDIR} and -isystem/usr/include so we override ISYSTEM.
This means any headers we stage for "host" will take precedence over
system headers but #include_next will DTRT.
src.init.linux.mk: add
-I${SRCTOP}/tools/build/cross-build/include/linux
and generally deal with building host tools on Linux.
Eg. static linking does not work so set NO_SHARED= no
Override some HAVE_ flags.
src.sys.env.mk: on linux awk throws an warning about # in newvers.sh
just send stderr to /dev/null

Move the setting of TARGET_SPEC_VARS to local.sys.env.mk
so meta.sys.mk can do the processing, and include local.meta.sys.mk
later.
Move the setting of GENDIRDEPS_FILTER*_VARS from local.gendirdeps.mk
to local.meta.sys.mk so we can automatically set DEP_* at level 1+
to avoid syntax errors when DEP_* variables are used in conditionals
in Makefile.depend files.
Update gendirdeps.mk just to get the documentation about the above.
No functional change.
local.dirdeps.mk be more careful about adding to DIRDEPS to avoid
unnecessary overhead, and introducing cycles in the graph.
Also set DEP_MACHINE_CPUARCH.

Several makefile depend on tools built for host.
At least when using DIRDEPS_BUILD we can build these for the

Ideally we would build these tools in their own directories to avoid
