install-info gnu subdir as it's the program updating the dir file. This
all has to happen because METALOG depends on _SRC_TOP_OBJ which is now
not defined in the top level Makefile per tv's last commit. Which is fine
as this rule should have gone into a program's Makefile anyways just like
the whatis.db one does.
not be the top level objdir, because "make obj" can happen in the *middle*
of "make build" (long after <bsd.own.mk> is calculated it). So, pre-set

different causes by users who forget to say that they are using

file's metadata if UNPRIVED and MKINFO != no. Make afterinstall depend
on it as well as whatis.db.
XXX I wish there was a more rational place to synthesize the metadata,
but I can't think of one. The share/info/dir file is built by all the
world's install-info executions.
* Rewrite src/tools Make logic to work like the rest of the tree wrt
"dependall" and "install". The old "make build" hack is gone.
* Remove the MKTOOLS logic. This was linked to the "make build" hack,
and was only needed because TOOLDIR originally had no writable default.
* Redo the GNU configure/make logic to make it fit reasonably in a
BSD make wrapper. Use new ${.ALLTARGETS} variable to scan for
targets in $(srcdir), and mark them with .MADE: to prevent rebuilding.
* Only build cross tools in src/tools; remove some messy logic in
src/usr.* and src/gnu/usr.* that would do target filename rewriting
(improves consistency and readability).
* Add the ability to build cross gdb at tool build time by setting
MKCROSSGDB (default no) to "yes" in mk.conf.
* Add src/tools/groff and set up paths to work with this cross groff.
just don't build the tools if USETOOLS!=yes. This permits objdirs to
be created even when USETOOLS=no.
* Clean up use of "-m" by specifying it to .MAKEFLAGS: if needed.
for broken builds is to fix the relevant Makefiles as was done for sparc.
This was done in the interest of simplicity of the system build (and the
fact that there may be a need to descend into these directories in the
near future).
subdir list as anything building into them will access them directly (ala
the make release rule or the mtree rule). There were good reasons for
controlling this at the top level before and those should remain in place.
On cleandir and obj builds these should get run through but that's it for
the "normal" rule sets. (This was breaking the builds as make includes doesn't
function inside of distrib for instance).
${USETOOLS} != "no"
to
${USETOOLS} == "yes"
to allow USETOOLS to be tri-state: "yes", "no", or "never". The use of
these options will be documented in src/BUILDING.
- "make build" cannot be invoked from the command line at the same time as
any standard recursive target except "obj" and "cleandir", as things like
"make all release" can lead to unexpected results.
- Put everything in SUBDIR, and auto-weed missing directories. This allows
the standard targets to work as expected (including in tools, etc, and
distrib).
- Leverage .for loops to simplify the prerequisite dependall/install phase
of compile-time dependencies (lib/csu, lib, gnu/lib). These are now all
distilled into one component rule ("do-build").
- Use the actual targets of obj, cleandir, and includes; no need for double
indirection goop in this case.
- GC all the deprecated "domestic" cruft. We are officially using (and
fixing, where appropriate) the cryptosystem integrated into src/crypto.
- Collapse the whatis.db build rule into a dependency of "afterinstall",
and nuke the "_BUILD" cruft.
variable TRUE defined in our makefile system.
This prevents "make includes" from breaking with older bsd.subdir.mk, and is
more consistent with the uses of "true" in the rest of the tree.

"make build"'s logic and the conventional <bsd.subdir.mk> logic probably
need to be split apart here at some point to prevent these kinds of things
from causing odd problems in the future....
file in order to get proper definitions for a build. (Temporary; this
Makefile will be moved to a new name and replaced with a bootstrap Makefile
in the near future.)
i386 platform builds must now set TOOLDIR in mk.conf or the
environment in order to build the system. This is a pathname
where host build tools will be installed, and must NOT be
the same as src/tools.
(Optionally, USETOOLS=no can be set in the environment if you
wish to avoid using the separate host toolchain for building a
subtree. Otherwise, this will default to "yes" automatically.)
However, building with USETOOLS=no set and no defined TOOLDIR ends up
with breakage, as the do-make-tools target is run regardless of whether
or not USETOOLS is set.
Hence, a wrapper around the body of the do-make-tools target:
.if ${USETOOLS} != "no"
...
.endif
...which makes the build work when USETOOLS=no, with no TOOLDIR set. This
would seem to more accurately match the description put forth in UPDATING.
In the new build world order, DESTDIR is set to "" (in Makefile.tools)
if not already set, to ensure correct include/library handling. This
caused the top-level to not set DESTDIR=/, which confused distrib-dirs,
since it doesn't include Makefile.tools, and thus didn't see the same
DESTDIR that the top-level did.
set, will descend into "tools" to build a toolchain, and use that toolchain
explicitly for the build (via tools/Makefile.tools).
While here, GC all the "egcs-detection" logic; it's not needed anymore, since
nothing is on gcc 2.7 any longer.

adding support for Heimdal/KTH Kerberos where easy to do so. Eliminate
bsd.crypto.mk.
There is still a bunch more work to do, but crypto is now more-or-less
fully merged into the base NetBSD distribution.
