Bryan Drewery 7f1636b75e Let SUBDIR_OVERRIDE with 'make buildworld' be more useful.
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

For copyright information, please see the file COPYRIGHT in this
directory (additional copyright information also exists for some
sources in this tree - please see the specific source directories for
more information).

The Makefile in this directory supports a number of targets for
building components (or all) of the FreeBSD source tree.  See build(7)
and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html
for more information, including setting make(1) variables.

The `buildkernel` and `installkernel` targets build and install
the kernel and the modules (see below).  Please see the top of
the Makefile in this directory for more information on the
standard build targets and compile-time flags.

Building a kernel is a somewhat more involved process.  See build(7), config(8),
and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html
for more information.

Note: If you want to build and install the kernel with the
`buildkernel` and `installkernel` targets, you might need to build
world before.  More information is available in the handbook.

The kernel configuration files reside in the sys/<arch>/conf
sub-directory.  GENERIC is the default configuration used in release builds.
NOTES contains entries and documentation for all possible
