Check whether the text+data+bss doesn't reach 0x6000 where secondary
bootloader should be.

Use ASSERT() in ldscript to check first_kbyte (etc) restrictions,
rather than complicated shell expressions in Makefile.

Change primary bootloader's load address from 0x0f0000 to 0x003000.
- Moving addresses closer eliminates bunch of this linker errors:
in function `entry0':
relocation truncated to fit: R_68K_16 against `edata'+ffffffffffff8000
:
- By this change, harmful -noinhibit-exec option can also be removed.
Finally, we can break the builds when assemble error occurs!
- Load address of secondary is 0x6000, so that this change limits
text+data+bss 12KB or less. Current actual size is 5~7KB.
I think it should be fine.
- cd9660 can have up to 30KB text+data in its bootarea. Even in this
case, this change limits text+data+bss 12KB or less (currently, it's
about 6KB). However, I take breaking the builds on errors rather than
future size limitation.
There is no user visible changes or interface changes.

Add 0x prefix when defining variables, not when using it.
This was necessary for bc(1) but it's no longer necessary.

Pass address constants from Makefile to ldscript.

Rewrite limit check using cross-build tools.
This eliminates use of hosts tr(1) and bc(1).

Fix "Error occurs, please reset" boot problem on
X68030 + 060turbo in 060 mode, found on NetBSD booth
at OSC 2011 Hiroshima:

- use -D__daddr_t=int32_t for all bootloader files
to avoid 64 bit ops in FFS
- explicitly specify -m68020-60 to avoid 64 bit mulsl/mulul
instructions which need to be handled by 060SP emulation
but not available in 060turbo IPL ROM
(LFS still has uint64_t members even with 32bit daddr_t)

The problem was investigated (at least 1.6.2 bootloaders worked)
by Yasushi Oshima at OSC booth, and fixes have been confirmed
by Y.Sugahara on his 060turbo. Thanks everyone!

Should also be pulled up to netbsd-5.

Drop bootprog_maker (formerly enabled by -M) and bootprog_date (formerly
disabled by -D) from the output of newvers_stand.sh. Change -D to the
inverted logic, so that it adds the date to bootprog_rev in ().

Change all platforms accordingly. -D is added if MKREPRO is not yes and
wasn't present before. Platforms that didn't use -D don't depend on
MKREPRO now either.

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
