a3bd401942 Don't recognize a file as an a.out shared library unless it has at
least 2 version numbers.  This fixes the bug where the dynamic
linker would try to load an ELF shared library if it found one.

Note, this change also fixes the same thing in "ld", because the
code is shared.

For "ld" there is still a problem with ".a" libraries, which cannot
be distinguished by name.  I haven't decided what, if anything, to
do about that.

32b8743969 Search for libraries in dlopen() when the specified path
contains no ``/''s.
Elf already searches it seems.

cabb97dcbf ELF preparation step 2:
Move a.out libraries to /usr/lib/aout to make space for ELF libs.
Make rtld usr /usr/lib/aout as default library path.
Make ldconfig reject /usr/lib as an a.out library path.
Fix various Makefiles for LIBDIR!=/usr/lib breakage.

This will after a make world & reboot give a system that no
longer uses /usr/lib/*, infact one could remove all the old
libraries there, they are not used anymore.

We are getting close to an ELF make world, but I'll let this
all settle for a week or two...

1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

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)

eb4a4eeb45 Split up the code so that a single directory can be searched, to
support some changes in the dynamic linker.  (This code is shared
by the dynamic linker.)

8af57ca9dd Removed /usr/local/lib from the standard library search path to be
consistant.  Programs shouldn't rely on non-standard paths for bringing
in default libraries.

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.

e86257e166 Change to
#define STANDARD_SEARCH_DIRS    "/usr/lib", "/usr/X11R6/lib", "/usr/local/lib"
Like in 2.0R, except without /usr/X386.

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.

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).

825079654d Remove /usr/X386/lib and /usr/local/lib from the default locations,
these are handled by /etc/rc and this was causing errors on a new
install as these places do NOT exsist by default!

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.
