fails when $# turns out to be 10 (or any multiple), it would need
to be instead
while [ $# -ge 10 ]; do shift 9; done
but there hasn't been a shell that cannot handle ${10} (etc) correctly
in a very long time, so let's just use that instead (properly quoted,
in case IFS happens to contain a digit for some bizarre reason).
We should also "set -f" / "set +f" (or better, restore the prev setting of -f)
around the "set $whatever" part, but if that was ever going to cause a problem
here, it would have already, so leave that for now.
were dealing with DBG (-d) LDSTATIC/NOPIE (-p), and the rest with
disabling/enabling sanitizers.
2. Use emalloc/estrdup for all the allocators instead of only some cases.
3. Add -V varspec which passes variables on the command line (as DBG
and LDSTATIC used to be passed before) instead of appending them
to the on-the-fly Makefile using -v varspec.
4. Change the distrib and rescue Makefiles to use -V instead of the removed
flags.
The motivation of this is to make variable handling consistent, less magical,
and remove the need for changing crunchgen each time we want to add disabling
an option by default.
(as proposed in tech-toolchain)
No program requires -ledit in crunched SMALLPROG case, and
miniroot doesn't have /usr/bin/file which requires -lmagic.
(sparc had it but it was removed in distrib/sparc/miniroot/list rev 1.29)

Make them all choose the former. No functional change.
in src/distrib/common/Makefile.image so that ${MAKESUMS} will be invoked
after the target image is installed into the releasedir, not before,
even if make -jN is specified.
XXX some ports do ${MAKESUMS} for installation/miniroot files
XXX in etc/etc.${MACHINE}/Makefile.inc later again.
md_view_labels() and a variable to mark its availability, so checking of
the available disklabels can be done before the root device is chosen.
Suggested by Martin Bertelsmann.
- move guts of distrib/Makefile.inc to distrib/common/Makefile.distrib
(fixes problem caused by implicit include of ../Makefile.inc in certain
submake conditions triggered by makefiles not yet in tree)
- removed mkdir of ${RELEASEDIR}/*; rely upon "snap_pre" target of
etc/Makefile to create all the release directories
- renamed RELINSTALL to RELEASE_INSTALL
- renamed FLOPPYINSTDIR to FLOPPY_RELEASEDIR
- renamed MDSETDIR to MDSET_RELEASEDIR
- removed ITARGET
- move release target from top level to appropriate subdirectory
- ensure release target has correct depends
- replace miniroot's IMAGE_MD_POST with common/Makefile.image IMAGEPOSTBUILD
- Makefile.image: add realall: ${IMAGE}
- improve comments
- provide a general purpose variable replacement; replace contents of ${FOO}
with ENVIRON["FOO"].
- deprecate @MACHINE@ and @MACHINE_ARCH@ in favour of using ${MACHINE}
and ${MACHINE_ARCH} instead
- add errx() function; like err(), but doesn't print the line number
- invoke this script with various variables defined via PARSELISTENV
*/Makefile*
- use PARSELISTENV instead of POPULATEENV, and add variables like DESTDIR
- other minor tweaks
*/list*
- replace @MACHINE@ with ${MACHINE}
dependent files:
- Use infrastructure from distrib/common to build file system images with
crunchgen-ed programs from a list file.
- Non root ("UNPRIVED") builds from a read-only source tree are possible,
as makefs(8) replaces vnconfig(8)/vnd use, devices are generated using
common/makedev2spec.awk, etc.
- Cross builds should be possible, except that some ports need cross-compile
host tool versions of installboot and any appropriate host disk labelling
tools.
XXX: pmax, sparc and vax need fixing for this!
- This code has NOT YET BEEN TESTED on most of the ports.
It should work, but it is extremely likely that the file system
parameters may need tweaking to get things to fit.
See MAKEFS_FLAGS in sparc/miniroot/Makefile.inc for an example.
