Now it can be used to effectively "build in a subdir". It will use the
'cross-tools', 'libraries', and 'includes' phases of 'buildworld' to properly
setup a WORLDTMP to use. Then it will build 'everything' only in the
listed SUBDIR_OVERRIDE directories. It is still required to list custom
library directories in LOCAL_LIB_DIRS if SUBDIR_OVERRIDE is something
that contains libraries outside of the normal area (such as
SUBDIR_OVERRIDE=contrib/ofed needing LOCAL_LIB_DIRS=contrib/ofed/usr.lib)
Without these changes, SUBDIR_OVERRIDE with buildworld was broken or hit
obscure failures due to missing libraries, includes, or cross compiler.
SUBDIR_OVERRIDE with 'make <target that is not buildworld>' will continue to
work as it did before although its usefulness is questionable.
With a fully populated WORLDTMP, building with a SUBDIR_OVERRIDE with
-DNO_CLEAN only takes a few minutes to start building the target
directories. This is still much better than building unneeded things via
'everything' when testing small subset changes. A BUILDFAST or
SKIPWORLDTMP might make sense for this as well.
- Add in '_worldtmp' as we still need to create WORLDTMP as later targets,
such as '_libraries' and '_includes' use it. This probably was avoiding
calling '_worldtmp' to not remove WORLDTMP for debugging purposes, but
-DNO_CLEAN can be used for that.
- '_legacy' must be included since '_build-tools' uses -legacy.
The SUBDIR_OVERRIDE change came in r95509, while -legacy being part
of build-tools came in r113136.
- 'bootstrap-tools' is still skipped as this feature is not for
upgrades.
- Fix buildworld combined with SUBDIR_OVERRIDE not installing all includes.
The original change for SUBDIR_OVERRIDE in r95509 kept '_includes'
and '_libraries' as building everything possible as the SUBDIR_OVERRIDE
could need anything from them. However in r96462 the real 'includes'
target was changed from manual sub-makes to just recursing 'includes'
on SUBDIR, thus not all includes have been installed into WORLDTMP since then
when combined with 'buildworld'.
This is not done unless calling 'make buildworld' as it would be
unexpected to have it go into all directories when doing 'make
SUBDIR_OVERRIDE=mydir includes'.
- Also need to build the cross-compiler so it is used with --sysroot.
If this is burdensome then telling the build to use the local compiler
as an external compiler (thus using a proper --sysroot to WORLDTMP) is
possible by setting CC=/usr/bin/cc, CXX=/usr/bin/c++, etc.
- Don't build the lib32 distribution with SUBDIR_OVERRIDE in buildworld
since it won't contain anything related to SUBDIR_OVERRIDE. Testing
of the lib32 build can be done with 'make build32'.
- Document these changes in build.7

This reverts r266473 as the need for it, working around .MAKE and '+'
issues, is no longer needed after r289460. This avoids extra log
output in -j builds of '-- _sub.TARGET --' that are redundant with the
'-- TARGET --' and '-- TARGET_subdir_DIR --' entries already showing.
r266473 also made a subtle change in the ordering of _SUBDIR handling. Before
the change, SUBDIRS were recursed into after building the TARGET due to the
.USE of _SUBDIR *appending* the commands onto the TARGET. After the change
though the indirection caused TARGET to depend on _sub.TARGET which had the
_SUBDIR handling in it. This TARGET would run after recursing. However, the
SUBDIR_PARALLEL handling from r263778 has this ordering as well. Since
this has so far not been a problem, for now make this behavior for
non-SUBDIR_PARALLEL use of _SUBDIR explicit by using .USEBEFORE.
Further research may change this back to .USE as well as the
SUBDIR_PARALLEL handling and bsd.progs.mk recursing.
Sponsored by: EMC / Isilon Storage Division
The SUBDIR_PARALLEL feature uses a .for dir in ${SUBDIR} loop. The old code
here for recursing was setting SUBDIR= as a make *argument*. The SUBDIR=
replacement was not actually handled until after the .for loop was unrolled.
This could be seen with a '.info ${SUBDIR} ${dir}' inside of the loop which
showed an empty ${SUBDIR} and a set ${dir}. Setting NO_SUBIDR= before calling
${MAKE} as an *environment* variable handles the case fine and is a more
proper mechanism for disabling subdir handling.
This could be seen with 'make -C tests/sys/kern -j15 SUBDIR_PARALLEL=yes'.

lookups.
This uses a special variable name based on a hash of ${CC}, ${PATH}, and
${MACHINE} to ensure that a cached value is not used if any of these
values changes to use a new compiler.
Before this there were 34,620 fork/exec from bsd.compiler.mk during a buildworld.
After this there are 608. More improvement is needed to cache a value from
the top-level before descending into subdirs in the various build phases.

Bmake has a documented feature of '-N' to skip executing commands which is
specifically intended for debugging top-level builds and not recursing into
sub-directories. This matches the older 'make -n' behavior we added which made
'-n -n' the recursing target and '-n' a non-recursing target.
Removing the '-n -n' feature allows the build to work as documented in
the bmake manpage with '-n' and '-N'. The older '-n -n' feature was also
not documented anywhere that I could see.
Note that the ${_+_} var is still needed as currently bmake incorrectly
executes '+' commands when '-N' is specified.
The '-n' and '-n -n' features were broken for several reasons prior to this.
r251748 made '_+_' never expand with '-n -n' which resulted in many
sub-directories not being visited until fixed 2 years later in r288391, and
many targets were given .MAKE over the past few years which resulted in
non-sub-make commands, such as rm and ln and mtree, to be executed.
This should also allow removing some indirection hacks in bsd.subdir.mk and
other cases of .USE that have a .MAKE by using '+'.

Before this, if a file was installed to DESTDIR/some/dir and that directory
was missing due to not having ran 'make distrib-dirs' yet, the file would
be installed as 'some/dir'. For something like bsd.incs.mk with INCLUDEDIR
being a sub-directory of /usr/include, this could result in all of the headers
being installed to a file rather than getting a directory of them.
Now it will error that the file/directory does not exist rather than hide
the issue.
Another option being discussed is to implement GNU's install -D flag which
would auto create any missing directories.
This is a mitigation of the problem. The proper order to the build is to
run 'make distrib-dirs' first, but that can be forgotten if building from
a sub-directory after updating the source code to the latest revision.

The 'config' target isn't really needed right now so just remove it to avoid

On each resolver query, use stat(2) to see if the modification time
of /etc/resolv.conf has changed. If so, reload the file and reinitialize
the resolver library. However, only call stat(2) if at least two seconds
have passed since the last call to stat(2), since calling it on every
query could kill performance.
This new behavior is enabled by default. Add a "reload-period" option
to disable it or change the period of the test.
Document this behavior and option in resolv.conf(5).
Polish the man page just enough to appease igor.

Before this, the target was unknown. Now it will recurse on subdirs and run
the target in the current directory. It is required to recurse as there
may be subdirs that have objs in their directory or in the object directory,
so it is not enough to just delete the objdir of the subdir parent.
