d0a184df5d Support for .weak (in addition to the N_INDR stab) for gcc/g++. Also deal
with the -R option and store the path in the dynamic header when specified.
The $LD_RUN_PATH environment variable is not checked yet.

While here, split up the code a bit more to enable more selective replacing
of GPL'ed components that are linked with ld.so with others.

Obtained from: NetBSD (mostly, the breakup is my fault)

c79eac4c4c Weak symbol support from NetBSD. This should bring us in sync with the
NetBSD ld code except for local changes for dlopen() and friends and
the hashing on the minor value of the shlibs.  We should be binary
compatible now with all their libraries.

61f9ce8d32 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
version of gas.

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.

699e1b82fb 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.

86a13e77dd Bug reported by Jon-Dean Mountjoy <csjm@cs.ru.ac.za>
Paul Kranenburg's description:
ld is in error here, assuming that symbols with N_EXT set always have an
entry in the (global) symbol table: this is not the case for C++ generated
constructor/destructor symbols. I can reproduce your failure by fudging
a "multiply defined" constructor symbol by hand. Checking for `g == NULL'
seems to be a ok as a fence for now.

So:
for now, in do_file_warnings() we check if g == NULL, before trying to generate
any warning messages.  This prevents a NULL pointer dereference.

09e3d49d92 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).

5b3dd4f53e 1. Fix bug where duplicate symbol warnings were suppressed. This often
caued ld to `exit silently', to general confusion.

2. Add Gary Jennejohn's fix to support debugging of shared libraries.

3923b0019c 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.
