Changes since 1.230: +3 -2 lines

Be more gcc like in the way we deal with libgcc so that sh3/hppa millicode
and exception handling have a chance of working properly.

        - creates libgcc, libgcc_eh and libgcc_s

        - updates LIBGCC_SPEC to use them appropriately.

          There's a hack in here at the moment with respect to libgcc_so in that it
          is preferable to link against libgcc_so will only when -shared-libgcc is
          specified (the c++ frontend does this automatically.) Configurations where
          LINK_EH_SPEC is defined already do this. The gcc configuration for
          NetBSD/alpha and another NetBSD platform (I forget which) actually define
          LINK_EH_SPEC probably by accident rather than design.

        - updates share/mk to use the compiler's knowledge of what needs linking into
          libraries and executables. This removes an hppa hack.

        - updates the sets for the newly created libgcc* files.

	- support for linking against the _pg version of libgcc has been removed.

#	$NetBSD: Makefile,v 1.231 2004/02/15 19:52:27 skrll 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 build', and then tars up the DESTDIR files
#	into RELEASEDIR/${MACHINE}, 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 ${RELEASEDIR}/${MACHINE}/binary/sets from ${DESTDIR}
#   sourcesets:
#	Populate ${RELEASEDIR}/source/sets from ${NETBSDSRCDIR}
# Targets invoked by `make build,' in order:
#   cleandir:        cleans the tree.
#   obj:             creates object directories.
#   do-tools:        builds host toolchain.
#   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-gnu-lib-libgcc3: builds and installs prerequisites from gnu/lib/libgcc3
#   do-lib-csu:      builds and installs prerequisites from lib/csu.
#   do-lib-libc:     builds and installs prerequisites from lib/libc.
#   do-lib-libdes:   builds and installs prerequisites from lib/libdes.
#   do-lib:          builds and installs prerequisites from lib.
#   do-gnu-lib:      builds and installs prerequisites from gnu/lib.
#   do-ld.so:        builds and installs prerequisites from libexec/ld.*_so.
#   do-build:        builds and installs the entire system.
#   do-x11:          builds and installs X11R6 from src/x11 if ${MKX11} != "no"
#   do-obsolete:     installs the obsolete sets (for the postinstall-* targets).
