Pass variables prefixed with both LD_ and LD_32_ to the run-time linker. This prevents unintentional execution of programs when running ldd(1) on 32-bit Linux binaries.

Tweak the support for using ldd on 32-bit objects a bit further. Specifically, build a 32-bit /usr/bin/ldd32 on amd64 which handles 32-bit objects. Since it is a 32-bit binary, it can fork a child process which can dlopen() a 32-bit shared library. The current 32-bit support in ldd can't do this because it does the dlopen() from a 64-bit process. In order to preserve an intuitive interface for users, the ldd binary automatically execs /usr/bin/ldd32 for 32-bit objects. The end result is that ldd on amd64 now transparently handles 32-bit shared libraries in addition to 32-bit binaries.

On 64 bit architectures, you can run 32 bit executables and the rtld can trace them, but ldd(1) doesn't know yet how to detect them:
[/] root@ed-exigent>ldd `which httpd` ldd: /usr/local/sbin/httpd: can't read program header ldd: /usr/local/sbin/httpd: not a dynamic executable
But...
[/] root@ed-exigent>LD_32_TRACE_LOADED_OBJECTS==1 `which httpd` libm.so.4 => /lib32//libm.so.4 (0x280c8000) libaprutil-1.so.2 => /usr/local/lib/libaprutil-1.so.2 (0x280de000) libexpat.so.6 => /usr/local/lib/libexpat.so.6 (0x280f2000) libiconv.so.3 => /usr/local/lib/libiconv.so.3 (0x28110000) libapr-1.so.2 => /usr/local/lib/libapr-1.so.2 (0x281fd000) libcrypt.so.3 => /lib32//libcrypt.so.3 (0x2821d000) libpthread.so.2 => not found (0x0) libc.so.6 => /lib32//libc.so.6 (0x28235000) libpthread.so.2 => /usr/lib32/libpthread.so.2 (0x2830d000)
Added support in ldd(1) for the LD_32_xxx environment variables if the architecture of the machine is >32 bits. If we ever go to 128 bit architectures this excercise will have to be repeated but thanks to earlier commits today it will be relative simple.

Fix a problem with RTLD_TRACE flag to dlopen(3), which sometimes can return even if there was no error occured (when trying to dlopen(3) object that already linked into executable which does dlopen(3) call). This is more proper fix for `ldd /usr/lib/libc.so' problem, because the new behaviour conforms to documentation.
Remove workaround from ldd.c (rev.1.32).

Fix a tiny bug in shlib support of ldd(1); if dlopen(lib, RTLD_TRACE) returns, exit gracefully with 0.
This fixes the behavior you see when you specify libc.so. It occurs because ldd(1) itself is linked with libc.so.
$ ldd /usr/lib/libc.so /usr/lib/libc.so: ldd: /usr/lib/libc.so: (null) /usr/lib/libc.so: exit status 1

* include/elf.h has been repo copied to include/elf-hints.h, and it no longer includes machine/elf.h. * consumers of elf.h now use the minimalist elf header possible.
This change is motivated by Binutils 2.11.0 and too much clashing over our base elf headers and the Binutils elf headers.

Changes from Paul Kranenburg which bring us into sync with his sources:
handling of errors through the standard err() and warn() more fixes for Geoff Rehmet's NULL pointer bug. fixes NULL pointer bugs when linking mono and nested X servers. supports a `-nostdlib' option. accept object files without a symbol table don't attempt dynamic linking when `-A' is given
a few variable names have chaged (desc -> fd), and the formatting has changed which should make it much easier to track his sources.
I tested 'make world' for /usr/src and X twice with these changes.

This is Paul K's latest set of ld changes. A commit was necessary at this late stage due to the fact that link.h was copyright Sun Microsystems.
This version of ld sync's us up with NetBSD's ld and supports compatablily with NetBSD's -[zZ] flags (which we had reversed). Compiling with this new ld will give you RRS warnings for libraries which do not contain .type infomation - these wsarnings are harmless and will go away as soon as you recompile your libraries (cd /usr/src; make libraries).

Updated to newest ld from pk.
lib.c: Pull in archives containing definitions needed by shared objects. warnings.c: Less spurious "undefined symbol" msgs for shared library defined symbols. ld.c: Do a better job of recognising data in text segments, eg. `const char []'. shlib.c,ld/rtld/{Makefile rtld.c} Use strsep() in stead of strtok() and restore colons in eg. env. vars.
