NetBSD/Makefile
mrg 4c92852a80 remove almost all the ability to build netbsd with an a.out target.
we're ELF now, and there are many missing checks against OBJECT_FMT.
if we ever consider switching, the we can figure out what new ones
we need but for now it's just clutter.

this doesn't remove any of the support for exec_aout or any actually
required-for-boot a.out support, only the ability to build a netbsd
release in a.out format.  ie, most of this code has been dead for
over a decade.

i've tested builds on vax, amd64, i386, mac68k, macppc, sparc, atari,
amiga, shark, cats, dreamcast, landisk, mmeye and x68k.  this covers
the 5 MACHINE_ARCH's affected, and all the other arch code touched.
it also includes some actual run-time testing of sparc, i386 and
shark, and i performed binary comparison upon amiga and x68k as well.


some minor details relevant:
- move shlib.[ch] from ld.aout_so into ldconfig proper, and cut them
  down to only the parts ldconfig needs
- remove various unused source files
- switch amiga bootblocks to using elf2bb.h instead of aout2bb.h

# $NetBSD: Makefile,v 1.278 2010/07/06 05:59:50 mrg Exp $
#
# This is the top-level makefile for building NetBSD. For an outline of
# how to build a snapshot or release, as well as other release engineering
# information, see http://www.NetBSD.org/developers/releng/index.html
#
# Not everything you can set or do is documented in this makefile. In
# particular, you should review the files in /usr/share/mk (especially
# bsd.README) for general information on building programs and writing
# Makefiles within this structure, and see the comments in src/etc/Makefile
# for further information on installation and release set options.
#
# Variables listed below can be set on the make command line (highest
# priority), in /etc/mk.conf (middle priority), or in the environment
# (lowest priority).
#
# Variables:
# DESTDIR is the target directory for installation of the compiled
# software. It defaults to /. Note that programs are built against
# libraries installed in DESTDIR.
# MKMAN, if `no', will prevent building of manual pages.
# MKOBJDIRS, if not `no', will build object directories at
# an appropriate point in a build.
# MKSHARE, if `no', will prevent building and installing
# anything in /usr/share.
# MKUPDATE, if not `no', will avoid a `make cleandir' at the start of
# `make build', as well as having the effects listed in
# /usr/share/mk/bsd.README.
# NOCLEANDIR, if defined, will avoid a `make cleandir' at the start
# of the `make build'.
# NOINCLUDES will avoid the `make includes' usually done by `make build'.
#
# See mk.conf(5) for more details.
#
#
# Targets:
# build:
# Builds a full release of NetBSD in DESTDIR, except for the
# /etc configuration files.
# If BUILD_DONE is set, this is an empty target.
# distribution:
# Builds a full release of NetBSD in DESTDIR, including the /etc
# configuration files.
# buildworld:
# As per `make distribution', except that it ensures that DESTDIR
# is not the root directory.
# installworld:
# Install the distribution from DESTDIR to INSTALLWORLDDIR (which
# defaults to the root directory). Ensures that INSTALLWORLDDIR
# is the not root directory if cross compiling.
# release:
# Does a `make distribution', and then tars up the DESTDIR files
# into ${RELEASEDIR}/${RELEASEMACHINEDIR}, in release(7) format.
# (See etc/Makefile for more information on this.)
# regression-tests:
# Runs the regression tests in "regress" on this host.
# sets:
# Populate ${RELEASEDIR}/${RELEASEMACHINEDIR}/binary/sets
# from ${DESTDIR}
# sourcesets:
# Populate ${RELEASEDIR}/source/sets from ${NETBSDSRCDIR}
# syspkgs:
# Populate ${RELEASEDIR}/${RELEASEMACHINEDIR}/binary/syspkgs
# from ${DESTDIR}
# iso-image:
# Create CD-ROM image in RELEASEDIR/iso.
# RELEASEDIR must already have been populated by `make release'
# or equivalent.
# iso-image-source:
# Create CD-ROM image with source in RELEASEDIR/iso.
# RELEASEDIR must already have been populated by
# `make release sourcesets' or equivalent.
#
# Targets invoked by `make build,' in order:
# cleandir: cleans the tree.
# do-top-obj: creates the top level object directory.
# do-tools-obj: creates object directories for the host toolchain.
# do-tools: builds host toolchain.
# obj: creates object directories.
# do-distrib-dirs: creates the distribution directories.
# includes: installs include files.
# do-tools-compat: builds the "libnbcompat" library; needed for some
# random host tool programs in the source tree.
# do-lib-csu: builds and installs prerequisites from lib/csu.
# do-libgcc: builds and installs prerequisites from
# gnu/lib/crtstuff${LIBGCC_EXT} (if necessary) and
# gnu/lib/libgcc${LIBGCC_EXT}.

# do-sys-rump-net-lib: builds and installs prerequisites from sys/rump/net/lib
# do-sys-modules: builds and installs kernel modules (used by rump binaries)
# do-ld.so: builds and installs prerequisites from libexec/ld.*_so.
# do-compat-lib-csu: builds and installs prerequisites from compat/lib/csu
# if ${MKCOMPAT} != "no".
# do-compat-libgcc: builds and installs prerequisites from
# compat/gnu/lib/crtstuff${LIBGCC_EXT} (if necessary) and
# compat/gnu/lib/libgcc${LIBGCC_EXT} if ${MKCOMPAT} != "no".
# do-compat-lib-libc: builds and installs prerequisites from compat/lib/libc
# if ${MKCOMPAT} != "no".
# do-build: builds and installs the entire system.
# do-x11: builds and installs X11 if ${MKX11} != "no"; either
# X11R7 from src/external/mit/xorg if ${X11FLAVOUR} == "Xorg"
# or X11R6 from src/x11
# do-extsrc: builds and installs extsrc if ${MKEXTSRC} != "no".
# do-obsolete: installs the obsolete sets (for the postinstall-* targets).
