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
