-dlopen self on AIX

[Albert Chin]

Does -dlopen self work on AIX? While building epiphany-1.6.5 on this
platform, seems that not all the correct symbols are being exported.
On AIX 5.3, dlopen_self=no. If -dlopen self is specified, then the
following code is executed (from the 1.5 branch):
          if test "$dlself" = yes; then
            $show "generating symbol list for \`$output'"

            test -z "$run" && $echo ': @PROGRAM@ ' > "$nlist"

            # Add our own program objects to the symbol list.
            progfiles=`$echo "X$objs$old_deplibs" | $SP2NL | $Xsed -e "$lo2o" | 
$NL2SP`
            for arg in $progfiles; do
              $show "extracting global C symbols from \`$arg'"
              $run eval "$NM $arg | $global_symbol_pipe >> '$nlist'"
            done
            ...

First, if noinst_LTLIBRARIES *.la files are specified on the
command-line, their symbol list will not be searched because the only
files searched for symbols is "X$objs$old_deplibs". This should really
be "X$objs$libobjs$old_deplibs$old_convenience".

Running the link line and the progfiles change I get:

One of the symbols not being exported is
"language_editor_up_button_clicked_cb". So, let's check out the above:
  $ grep language_editor_up_button_clicked_cb .libs/epiphanyS.c
  {"language_editor_up_button_clicked_cb", (lt_ptr) 
&language_editor_up_button_clicked_cb},
  $ nm -BCpg .libs/epiphanyS.o | grep language_editor_up_button_clicked_cb
         - U language_editor_up_button_clicked_cb
  $ nm -BCpg epiphany | grep language_editor_up_button_clicked_cb
  269185316 T .language_editor_up_button_clicked_cb

But what I want is the following:
  $ nm -BCpg epiphany | grep language_editor_up_button_clicked_cb
  269185316 T .language_editor_up_button_clicked_cb
  536936672 D language_editor_up_button_clicked_cb
