    Don't build readline's shared libs by default
    
    Since the sync to version 7.0-alpho, readline now by default builds
    (unused) shared libraries alongside static libraries, whereas before it
    only built static libraries.  A couple of GDB buildbots were not happy
    with this change:
    
      http://gdb-build.sergiodj.net/builders/AIX-POWER7-plain/builds/240
      http://gdb-build.sergiodj.net/builders/Fedora-i686/builds/1518
    
    To get these buildbots building again, this patch alters readline's
    configure.ac file to not build shared libraries by default, as was the
    case with readline 6.2.  A more permanent fix may be to alter the
    top-level Makefile.def to pass --disable-shared to readline, or to
    investigate why these building these shared libraries are giving the
    buildbots trouble.  (I think the proximate reason why the i686 buildbot
    fails is because it passes CFLAGS=-m32 instead of CC="gcc -m32" to the
    top-level configure script, and readline's linker commands don't inherit
    CFLAGS.  Not sure about the AIX failure.)
    
    readline/ChangeLog.gdb:
    
    	* configure.ac: Default opt_shared_libs to no.
    	* configure: Regenerate.
