Lionel Sambuc 9152e1c5a7 Upgrading build system to new NetBSD revision 
The tested targets are the followgin ones:
 * tools
 * distribution
 * sets
 * release

The remaining NetBSD targets have not been disabled nor tested
*at all*. Try them at your own risk, they may reboot the earth.

For all compliant Makefiles, objects and generated files are put in
MAKEOBJDIR, which means you can now keep objects between two branch
switching. Same for DESTDIR, please refer to build.sh options.

Regarding new or modifications of Makefiles a few things:
 * Read share/mk/bsd.README
 * If you add a subdirectory, add a Makefile in it, and have it called
   by the parent through the SUBDIR variable.
 * Do not add arbitrary inclusion which crosses to another branch of
   the hierarchy; If you can't do without it, put a comment on why.
   If possible, do not use inclusion at all.
 * Use as much as possible the infrastructure, it is here to make
   life easier, do not fight it.

Sets and package are now used to track files.
We have one set called "minix", composed of one package called "minix-sys"

# Makefile to create a bootable FS image for USB flash or emulators

# set yes if target disk image requires MBR partition
# (default: no)
# MBR_BOOTCODE
# optional MBR bootcode which should be installed by fdisk(8)
# (default: empty)
# - specified MBR_BOOTCODE must exist in ${DESTDIR}/usr/mdec
# - if MBR_BOOTCODE is not specified,
# MBR_DEFAULT_BOOTCODE (default: mbr) will be used

# USE_SUNLABEL
# set yes if target disk image requires Sun's label

# target image size in MB
# (default: 2048)
# SWAPMB
# swap size in target image in MB

# binary sets that should be extracted into image
# (default: modules base etc comp games man misc tests text
# xbase xcomp xetc xfont xserver)
# SETS_DIR
# directory path where binary sets are stored
# (default: ${RELEASEDIR}/${RELEASEMACHINEDIR}/binary/sets)

# FILE TARGETPATH
# for installation image etc.
# (default: empty)
# IMGDIR_EXTRA
# list of additional directories to be copied into images,
# containing one or more tuples of the form:
# DIR TARGETPATH
# for installation image etc.
# (default: empty)
# XXX: currently permissions in IMGDIR_EXTRA are not handled
# IMGDIR_EXCLUDE
# pax(1) options to exclude files which should not copied
# into TARGETPATH in IMGDIR_EXTRA
# (default: empty)

# default files of spec file for makefs(8)
# (default: ${DISTRIBDIR}/common/bootimage/spec.in)

# additional files of spec file for makefs(8)
# (default: empty)

# primary boot loader that should be installed into
# the target image via installboot(8)
# (default: empty)
# SECONDARY_BOOT
# secondary bootloader that should be put into the target image

# extra arguments that should be passed to installboot(8)
# to specify the secondary bootloader
# (default: empty)
# DISKPROTO_IN
# template file of disklabel -R
# (default: ${DISTRIBDIR}/common/bootimage/diskproto.in
