joerg 9d3b3e9cc5 Fix ldd on LP64 platforms by splitting the symbol versioning stuff for
elf64 as well.

joerg aad599979d Add TLS support infrastructure. For dynamic binaries, ld.elf_so exports
_rtld_tls_allocate and _rtld_tls_free. libpthread uses this functions to
setup the thread private area of all new threads. ld.elf_so is
responsible for setting up the private area for the initial thread.
Similar functions are called from _libc_init for static binaries, using
dl_iterate_phdr to access the ELF Program Header.

Add test cases to exercise the different TLS storage models. Test cases
are compiled and installed on all platforms, but are skipped on
platforms not marked for TLS support.

This material is based upon work partially supported by
The NetBSD Foundation under a contract with Joerg Sonnenberger.

It is inspired by the TLS support in FreeBSD by Doug Rabson and the
clean ups of the DragonFly port of the original FreeBSD modifications.

mrg 118cb193d7 - adjust the logic for compat ldd: add an elf32_compat module and arrange
for mips64 to build this with MLIBDIR set to o32
- make mips64 ldd call elf32_compat_ldd as well
- make mips64 elf64 set MLIBDIR to 64
- don't need ld.elf_so's Makefile.ld32 files anymore (they are going away
  soon anyway)

tested on amd64 and sparc64, and an earlier version tested on mips64.

mrg 32ae7959e8 make sure we set LIBISPRIVATE.
fixes build issues reported by moof.

mrg 9b688fed42 - rework this a bunch to make it work inside /rescue/ldd.
- fix alpha build.

mrg 648c936726 - get rid of building an a.out-happy ldd (but keep supporting a.out
binaries for the ELF version.)

- convert a.out, elf32 and elf64 support into convience libraries and
  link them right ones in.  if elf_ldd() fails on 64 bit platforms,
  try elf32_ldd() before aout_ldd().


now ldd on 64 bit platforms works for 32 bit binaries, aka PR#40199,
and it seems that all the issues from README are gone too.
