    Fix gdb.ada/arrayptr.exp results
    
    PR ada/28115 points out that gdb.ada/arrayptr.exp works with GNAT 12,
    but fails with minimal encodings in earlier versions.
    
    This patch updates the test to try to report the results correctly.  I
    tried this with the Fedora 34 system gcc (GCC 11) and with a GCC 12
    built from git trunk sometime relatively recently.
    
    Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=28115
