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"

#
# Rules used when building a GNU host package. Expects MODULE to be set.
#
# There's not a lot we can do to build reliably in the face of many
# available configuration options. To be as low-overhead as possible,
# we follow the following scheme:
#
# * Configuration is only re-run when an autoconf source file (such as
# "configure" or "config.sub") is changed.
#
# * "config.status" is run to rebuild Makefiles and .h files if an
# autoconf-parsed file (such as Makefile.in) is changed.
#
# * If MKUPDATE != "no", "make install" is only run if a build has happened
# since the last install in the current directory.
