dynamic linker.

that is stored in the hints file. If that search path contained
a non-existent directory (one, say, that had been removed), and
"ldconfig -m /a/perfectly/good/directory" was run, ldconfig returned
an error status without printing an error message. This caused
some confusing bombs when installing ports, in particular.
I changed it so that non-existent directories from the stored search
path are silently ignored. Only non-existent directories named
explicitly on the command line are treated as errors. Also, a
diagnostic is printed if and only if an error status is returned.
In an unrelated fix, ldconfig now silently ignores any directories
named on the command line when the "-r" option is given. Formerly,
these directories incorrectly made their way into the "search
directories" line of the listing. It really should be an error to
specify directories together with "-r", but I don't have time to
fix the manual page in that way right now.

Remove various bogus pathnames to look up rsh(1) at. Our rsh is in

The code in crt0.o for printing error messages from the dynamic linker

backward compatibility with older dynamic linkers.

libg++'s exception code causes gcc to generate (ahem!) non-conventional
assembler code in -fpic mode that gas and ld choke on. Basically, gas
and ld require than symbols referenced in the GOT (global offset table)
are actually global (as the name implies). It attempted to work around
it before, but didn't quite go far enough to prevent a core dump in ld.
This hack causes GOT referenced symbols to be forced global. This
probably breaks the __EXCEPTION_TABLE__ stuff in pic mode, but heck, it
wasn't even possible to compile with a shared library before at all.
I'm not 100% sure what the bug is. There's two possibilities:
1: gcc/cp/exception.c has to be fixed to stop doing GOT references to
local symbols, or
2: as/ld/symorder/ld.so etc need to be taught about how to keep local
symbols around so that they can be dealt with in GOT references.
John Polstra's elfkit stuff seems to deal with this fine though, which is
why I think it's a "missing feature" in our hacked gas and ld..

Also:

The library search sequence is a little more complete now. Before,
it'd search $LD_LIBRARY_PATH (by opendir/readdir/closedir), then read
the hints file, then read /usr/lib (again by scanning thr directory). It
would then fail if there was no "found" library.
Now, it does LD_LIBRARY_PATH and the hints file the same, but then uses
a longer fallback path. The -R path is fetched from the executable if
specified at build time, the ldconfig path is appended, and /usr/lib is
appended to that. Duplicates are suppressed. This means that simply
placing a new library in /usr/local/lib will work (the same as it did in
/usr/lib) without needing ldconfig -m. It will find it quicker if the
ldconfig is run though.
Similar changes have been made to the NetBSD ld.so, but ours is rather
different now due to John Polstra's speedups and fixes from a while back.
The ldd printf-like format support came direct from NetBSD.
