libtool 1.4 branch and IRIX 6.x

[Albert Chin]

When using CC=cc on IRIX 6.x, ld is used to create shared libraries.
However:
  hardcode_libdir_flag_spec='${wl}-rpath ${wl}$libdir'

This causes -Wl,-rpath to be passed to ld. Unfortunately, ld
recognizes -rpath but not -Wl so we get errors like:
  (null): WARNING 1  : Unknown option: Wl,-rpath (ignored).

So, the solution would seem to be the patch below. However, after
applying this patch and running 'make check', build-relink2 dies at
the end:
  if test "$shlibpath_overrides_runpath" != yes; then
    rm -f $objdir/lt-depdemo || exit 1
    cp $objdir/depdemo $objdir/lt-depdemo || exit 1
    echo "running ../depdemo/depdemo with installed libl3.la"
    if ./depdemo; then
      echo "Worked, as expected"
    else
      echo "shlibpath_overrides_runpath should be set to yes"
      status=1
    fi
    rm -f $objdir/lt-depdemo
  fi

For IRIX 6.x:
  shlibpath_overrides_runpath = no
because, according to rld(5):
  The search path for shared objects is as follows:

  1. The path of the shared object, if specified in the liblist.  That
     is, if the soname of the shared object has a path.  For more
     information, see the ld(1) man page.

  2. DT_RPATH, if it is defined in the executable or any DSO that rld
     has opened.

  3. Use LD_LIBRARY_PATH, if it is defined in the environment at the
     time of execution.

  4. The default library search path.

However:
  $ elfdump -L depdemo/.libs/depdemo | grep RPATH
  
/opt/build/libtool-1.4.2/depdemo/l1/.libs:/opt/build/libtool-1.4.2/tests/_inst/lib:/opt/build/libtool-1.4.2/depdemo/l2/.libs:/opt/build/libtool-1.4.2/depdemo/l3/.libs:/opt/build/libtool-1.4.2/tests/_inst/lib/extra

Both /opt/build/libtool-1.4.2/depdemo/l3/.libs and
/opt/build/libtool-1.4.2/tests/_inst/lib/extra contain libl3.so.1.0 so
the version in /opt/build/libtool-1.4.2/depdemo/l3/.libs is selected
as it is first in the search path. However, before the
shlibpath_overrides_runpath test, we broke libl3.so.1.0 earlier in
build-relink2 so libl3.so.1.0 does not contain var_l3. This results
in:
  $ .libs/depdemo
  174396:./depdemo: rld: Error: unresolvable symbol in
/opt/build/libtool-1.4.2/tests/_inst/lib/libl4.so.1: var_l3
  174396:./depdemo: rld: Fatal Error: this executable has unresolvable
symbols

causing the test to fail. So, is build-relink2.test broken?
