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

make MKPIC=no builds work on i368, shark, vax, pmax, sgimips, sparc,
maybe all mips and all arm as well.

MKDYNAMICROOT for a.out

Use ${NETBSDSRCDIR}/some/path instead of ${.CURDIR}/../../some/path

Also build ldconfig is MACHINE_ARCH is arm or vax buf OBJECT_FMT=ELF

Make and install ldconfig on ELF m68k ports.

Modification to previous: only build for ports that are a.out or used
to be a.out. No sense in building for ports that never were a.out.

Build this on ELF as well. When on an ELF system, only look in
_PATH_EMUL_AOUT/etc/ld.so.conf.

Only build ldconfig on a.out platforms. Everyone else still builds the

- don't core-dump if hints file is too short
- unmap the space and close fd's
- bcopy -> memcpy
- stat the file to get the size to map, instead of doing multiple mmaps.

MAP_COPY -> MAP_PRIVATE

Plug a file descriptor leak.

Fill in missing (default) mmap(2) flags.

Enhancements from Jim Bernard <jbernard@tater.mines.edu>, to support
processing of /etc/ld.so.conf in ld.so itself (rather than in /etc/rc):
- added do_conf function and call to it in main to implement internal
processing of /etc/ld.so.conf
- moved maintenance of dir_list to dodir, with an added argument to
dodir to specify whether dir_list should be updated
- added option '-c' to suppress processing of /etc/ld.so.conf
- added option '-S' to suppress processing of std directories (but not
/etc/ld.so.conf)
- modified option -s to suppress processing of _both_ std directories
and /etc/ld.so.conf (i.e., it is equivalent to -cS)--this was done
so that users and scripts that interpret -s as meaning "process
only directories specified on the command line" would not be
startled

From PR #4031. One change was not committed, since it was unnecessary
(option variables are in the BSS, and do not need to be initialized to
0 explicitly).

Plus one change from me:
- getopt() returns -1 when completed, not EOF.

mktemp() -> mkstemp()
