Build release notes if groff is present (MKGROFF!=no), not if man pages
are requested (MKMAN!=no).

Add "live-image" and "install-image" target support to build.sh.

"live-image" target builds pre-installed disk images that can be used on
emulators or boot from USB memory sticks to try NetBSD without installation.
Currently amd64, i386, pmax, sparc, sparc64, sun2, sun3, and vax
(which have working emulators and don't require extra tools like preparing
msdosfs or partitioning MD label structures) support this target.

"install-image" target builds an bootable installation disk image that can
be used as an install CD but burned into USB memory sticks etc.
Current only amd64 and i386 (which would support USB boot) have this target.

No particular comments about implementation, and
"go ahead" comments from mrg@, riz@ and christos@.

Closes PR toolchain/45153 and PR misc/45155.

Build in 'utils' subdir before building miniroot, or the MD bits.
When making changes to 'sysinst', for example, one would expect them
reflected in the generated installers.

branches: 1.16.8;
Create a dynamically linked sysinst as part of the build process, but don't
install it.

Don't descend into distrib/notes if MKMAN==no, because
groff (et al) isn't available in $TOOLDIR in that situation.
Fixes PR 30675.
(If we ever implement more specific "don't build groff" or "don't build C++"
build knobs, we can change this to use that.)

branches: 1.14.12; 1.14.16;
Add an iso_image target (iso-image as a target name doesn't play well with
bsd.subdirs.mk) in distrib/makefile, which builds an iso image for $MACHINE
with binary sets, stored in ${RELEASEDIR}/iso. The image is bootable for:
alpha, amd64, cats, i386, pmax, sgimips, sparc, sparc64, sun3, vax.
mac68k/macppc no there yet because of missing feature in makefs.

call iso_image in distrib/ for iso-image in the top Makefile.

branches: 1.13.10;
``build.sh -m xen-i386 release'' now builds a release for NetBSD/xen
for i386. The resulting release consists of:
- NetBSD/xen for i386 kernel, loader and docuemntation
- NetBSD/i386 userland sets

descend to utils if we are making obj

branches: 1.11.4;
Need to wait after making the notes in case the port uses them later on.

add TARGETS+=release

branches: 1.9.2;
.WAIT on miniroot, as some ports (such as sparc) need it built for
later steps to operate

don't descend into utils as it's not necessary with recent crunchgens

Revert previous, and add back "utils" to SUBDIRS.
I accidentally committed the previous rev with the wrong commit message
(thanks go to Nick Hudson <skrll@netbsd.org> for picking this up).
Eventually we will probably want to stop descending into utils, but
now is not that time.

tweak the size from 4500k to 4480k, which is on a cyl group boundary

only descend into miniroot if ${MACHINE}/miniroot/Makefile.inc exists

undo previous (test)

whitespace-change
[log_accom test for committing to >1 module]

Enter the notes subdir before entering the machine directories.
This is needed, at least for the alpha, to get the INSTALL.more doc.

Descend into ./utils and ./notes, possibly into ./miniroot and also
into ./${MACHINE} if ${MACHINE}/Makefile exists. (None do right now.)
