acfd35dad9 PR/44010: YAMAMOTO Takashi: sbrk: grow 0xb3ba2000 failed, error = 12" 
(due to setenv changes?)
Provide a mini unsetenv that does not allocate/free memory and does not
bother about locking.

06acf46b03 Introduce a new type Elf_Symindx for use in decoding the symbol hash table 
section and allow this type to be overridden.

The ELF specification says it should always be uint32_t (Elf_Word), but
alpha decided to be different (not sure why). Define Elf_Symindx to be
uint64_t on alpha.

Alpha no longer uses non-standard definitions of Elf64_Sword and
Elf64_Word.  Remove the ability to override these types.

Fixes ld.elf_so after Herculean effort from me and martin.

4c92852a80 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

ff0f2fb483 Use fast_remainder32 for the ELF hash. For the hot cache case, this 
speeds up Firefox startup by over 2% on AMD64.
