Update some distrib X11R6 references to X11R7

Some of these scripts and notes may no longer be relevant, but now
they are at least not relevant while referring to the current X
installation directory

Use ${TOOL_GZIP_N} instead of ${TOOL_GZIP} -n, and similarly
use ${TOOL_GZIP_N} -9 instead of ${TOOL_GZIP} -9n, etc.

This will pass -nT instead of just -n if the gzip program is
actually pigz.

branches: 1.30.2;
Use ${TOOL_GZIP} instead of just gzip in all Makefiles
outside */dist/* subdirectories.

When USE_PIGZGZIP=yes, bsd.own.mk sets TOOL_GZIP=${TOOL_PIGZ},
so there's no need to test USE_PIGZGZIP in these Makefiles.

branches: 1.29.6; 1.29.12;
Consistently use gzip with the -n flag so dates are not embedded.

Not tested on all platforms.

branches: 1.28.32; 1.28.42;
Rename a large chunk of the make(1) variables which refer to a
program/tool from "FOO" to "TOOL_FOO". The new variables are:
TOOL_ASN1_COMPILE TOOL_CAP_MKDB TOOL_CAT TOOL_CKSUM TOOL_COMPILE_ET
TOOL_CONFIG TOOL_CRUNCHGEN TOOL_CTAGS TOOL_DB TOOL_EQN TOOL_FGEN
TOOL_GENCAT TOOL_GROFF TOOL_HEXDUMP TOOL_INDXBIB TOOL_INSTALLBOOT
TOOL_INSTALL_INFO TOOL_M4 TOOL_MAKEFS TOOL_MAKEINFO TOOL_MAKEWHATIS
TOOL_MDSETIMAGE TOOL_MENUC TOOL_MKCSMAPPER TOOL_MKESDB
TOOL_MKLOCALE TOOL_MKMAGIC TOOL_MKTEMP TOOL_MSGC TOOL_MTREE
TOOL_PAX TOOL_PIC TOOL_PREPMKBOOTIMAGE TOOL_PWD_MKDB TOOL_REFER
TOOL_ROFF_ASCII TOOL_ROFF_DVI TOOL_ROFF_HTML TOOL_ROFF_PS
TOOL_ROFF_RAW TOOL_RPCGEN TOOL_SOELIM TOOL_SUNLABEL TOOL_TBL
TOOL_UUDECODE TOOL_VGRIND TOOL_ZIC

For each, provide default in <bsd.sys.mk> of the form:
TOOL_FOO?= foo
and for the ${USETOOLS}=="yes" case in <bsd.own.mk>, provide override:
TOOL_FOO= ${TOOLDIR}/bin/${_TOOL_PREFIX}foo

Document all of these in bsd.README.

This cleans up a chunk of potential (and actual) namespace collision
within our build infrastructure, as well as improves consistency in
the share/mk documentation and provision of appropriate defaults for
each of these variables.

migrate to /usr/sbin/installboot or ${INSTALLBOOT} as appropriate

TARGETS is defined by bsd.own.mk, so use LOCALTARGETS instead

Use
${MAKE}
instead of
make

use bsd.kernobj.mk to tell us KERNOBJDIR for compiled kernels.

adjust for changes in alpha /usr/mdec files.

branches: 1.22.2;
Modify all calls to newfs in ramdisk/miniroot creation to include
the needed endianism of the architecture. One step towards cross-building
releases.

Not touched are newfs calls in install scripts as they run on the desired
machine and thus default correctly.

distclean is a synonym for cleandir

Don't use _SUBDIRUSE outside of bsd.subdir.mk.

rcs id cleanups

punt rc.hack for now. It's not so happy with a shared-lib-based system,
because it wants to use sysctl and sysctl is normally dynamically linked,
and it doesn't have the shared libs available when it wants to use it.
The right thing to do (if i want to propagate this hack) is to build a
statically-linked sysctl rather than copying the dynamically-linked one.

clean up in various ways

when checking the built file systems, force the check (use -f), and make
sure fsck is trying to check ffs file systems (use -t ffs) because it's
not smart enough to figure that out on its own.

>(remounts root read-write, mounts /usr, etc.) includes instructions

Be more tolerant of changes in the GNU (Cygnus) cpp binary's location
due to NetBSD and Cygnus release number/date changes.

branches: 1.13.4;
update for new X, toolchain source locations, and for the new
location of the toolchain's cpp (caused by the change in 'uname -r' caused
by the merge with the master sources).

repoint libexec/cpp link to the right place. grn.

add missing . to libexec/cpp symlink, as pointed out by John Birrell

update for new way of doing boot block, don't include /boot in bin.tar.gz

don't include X11 bins or kernel in the bin.tar.gz file

slight cleanup, add target to build x11 bins tar file.

rearrange dependencies so that this actually works.

no longer need the MAKEDEV invocation here.

build some tar files, too.

copy boot program to / from /usr/mdec

cpp (for symlink from /usr/libexec/cpp) has moved

/usr/src/devo on the alpha has been renamed to /usr/src/cygnus

make an alpha distribution disk. includes newfs, of a SCSI disk! whee!
