external/lib/Makefile and crypto/external/lib/Makefile, replacing
them all with SUBDIRs directly from lib/Makefile.
compat/compatsubdirs.mk becomes simpler now, as everything is built
from lib/Makefile, meaning all the libraries will now be built under
compat so update the set lists to account for that.
local definitions of
ASM_PREFERRED_EH_DATA_FORMAT
ASM_MAYBE_OUTPUT_ENCODED_ADDR_RTX
and make it obvious we're not using local ASM_OUTPUT_INTERNAL_LABEL
This fixes the current build problems (and probably more)
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
mknative-gdb to generate these, but my initial attempt failed and
these ones seem to be about what i'd expect anyway.

most of them are most harmless, but the libgcc parts are quite essential.
before this change, all the special rules for .pico files were not applied,
and exception handling wasn't enabled. this caused c++ exceptions not to
work on sparc64.
this fixes the build of boost-headers (it was correctly calling exception
support broken!), which in turn makes all the things that depend upon it
to actually work again on sparc64.
