66c935d52f 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

538e761e02 * 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.

7f56eb7b93 Updated to recent version of Paul K.'s shlib code. This code has better 
warning handling and allows for link-time warnings with a modified

Note: Not all of the newer bits were updated such as some of the non-x86
machine-dependant code is relevant to FreeBSD right now.

c2b2b84657 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.

477937c24f 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).
