lt_dlopen() bad behaviour on AIX

[Laurent Vivier]

On AIX(powerpc-ibm-aix4.3.2.0), using library with name of the kind
lib<name>.a, lt_dlopen()
cannot find library if provided name is lib<name>.so and don't return
any error code to allow to seek the library using lib<name>.la.

To correct the problem, I propose the following solution:

*** ../link/src/libtool/libltdl/ltdl.c  Tue Sep 11 04:02:07 2001
--- libtool/libltdl/ltdl.c      Fri Jun 14 11:10:30 2002

        {

        if (!newhandle)
        {

                   )))
        {
!         if (tryall_dlopen (&newhandle, filename) != 0)
!         {
!            newhandle = 0;
!         }
!       }
  
        if (!newhandle)
