This is not properly respecting WITHOUT or ARCH dependencies in target/.
Doing so requires a massive effort to rework targets/ to do so. A
better approach will be to either include the SUBDIR Makefiles directly
and map to DIRDEPS or just dynamically lookup the SUBDIR. These lose
the benefit of having a userland/lib, userland/libexec, etc, though and
results in a massive package. The current implementation of targets/ is

META MODE: Rework [bootstrapped] tools PATH support.
- Support more of the toolchain from TOOLSDIR.
- This also improves 'make bootstrap-tools' to pass, for example,
AS=/usr/bin/as to Makefile.inc1, which will tell cross-tools to use
external toolchain support and avoid building things we won't be using
in the build.
- Always set the PATH to contain the staged TOOLSDIR directories when
not building the bootstrap targets.
The previous version was only setting this at MAKE.LEVEL==0 and if the
TOOLSDIR existed. Both of these prevented using staged tools that were
built during the build though as DIRDEPS with .host dependencies, such
as the fix for needing usr.bin/localedef.host in r291311.
This is not a common tool so we must build and use it during the build,
and need to be prepared to change PATH as soon as it appears.
This should also fix the issue of host dependencies disappearing from
Makefile.depend and then reappearing due to the start of the fresh build not
having the directory yet, resulting in the tools that were built not actually
being used.
- Only use LEGACY_TOOLS while building in Makefile.inc1. After r291317
and r291546 there is no need to add LEGACY_TOOLS into the PATH for
the pseudo/targets/toolchain build.
- Because the pseudo/targets/toolchain will now build its own
[clang-]tblgen, the special logic in clang.build.mk is no longer needed.
- LEGACY_TOOLS is no longer used outside of targets/pseudo/bootstrap-tools
so is no longer passed into the environment in its build.

None of usr.bin/clang/clang-tblgen or its dependencies need

As the kernel allocates and frees vnodes, it fully initializes them
on every allocation and fully releases them on every free. These
are not trivial costs: it starts by zeroing a large structure then
initializes a mutex, a lock manager lock, an rw lock, four lists,
and six pointers. And looking at vfs.vnodes_created, these operations
are being done millions of times an hour on a busy machine.
As a performance optimization, this code update uses the uma_init
and uma_fini routines to do these initializations and cleanups only
as the vnodes enter and leave the vnode_zone. With this change the
initializations are only done kern.maxvnodes times at system startup
and then only rarely again. The frees are done only if the vnode_zone
shrinks which never happens in practice. For those curious about the
avoided work, look at the vnode_init() and vnode_fini() functions in
kern/vfs_subr.c to see the code that has been removed from the main
vnode allocation/free path.

For performance reasons, it is useful to have a single string used as
the name of a filesystem when setting it as the first parameter to the
getnewvnode() function. Most filesystems call getnewvnode from just one
place so can use a literal string as the first parameter. However, NFS
calls getnewvnode from two places, so we create a global constant string
that can be used by the two instances. This change also collapses two
instances of getnewvnode() in the UFS filesystem to a single call.
User and group identifiers the rctl(8) utility receives from the kernel
are always in numeric form; don't try to resolve them by names. This
speeds up rule listing with large rulesets by about 50%.

sfxge: modify nvram update functions for uio platform to support RFID-selectable presets
Dynamic config partitions on boards that support RFID are divided into
a number of segments, each formatted like a partition, with header,
trailer and end tags. The first segment is the current active
configuration.
The segments are initialised by manftest and each contain a different
configuration e.g. firmware variant. The firmware can be instructed
via RFID to copy a segment over the first segment, hence changing the
active configuration. This allows ops to change the configuration of
a board prior to shipment using RFID.
Changes to the dynamic config may need to be written to all segments (in
particular firmware versions written by manftest) or just the first
segment (changes to the active configuration). See SF-111324-SW.
If only the first segment is written the code still needs to be aware of
the possible presence of subsequent segments as writing to a segment may
cause its size to increase, which would overwrite the subsequent
segments and invalidate them.
Boards that do not support RFID will only have one segment in their
dynamic config partition.
