    [gdb/testssuite] Skip aarch64 in skip_gdbserver_test if no xml support
    
    On aarch64-linux, with a gdb build without libexpat, so without xml support, I
    run into:
    ...
    (gdb) builtin_spawn attach-no-multi-process^M
    attach 26808^M
    Attaching to Remote target^M
    warning: Can not parse XML target description; XML support was disabled at \
      compile time^M
    Reading symbols from attach-no-multi-process...^M
    Remote 'g' packet reply is too long (expected 788 bytes, got 796 bytes): ... ^M
    ...
    
    The test-case checks for skip_gdbserver_tests and that one contains a check
    for xml support:
    ...
        # If GDB is lack of XML support, and targets, like arm, have
        # multiple target descriptions, GDB doesn't know which target
        # description GDBserver uses, and may fail to parse 'g' packet
        # after connection.
        if { [gdb_skip_xml_test]
             && ([istarget "arm*-*-linux*"]
                  || [istarget "mips*-*-linux*"]
                  || [istarget "powerpc*-*-linux*"]
                  || [istarget "s390*-*-linux*"]
                  || [istarget "x86_64-*-linux*"]
                  || [istarget "i\[34567\]86-*-linux*"]) } {
            return 1
        }
    ...
    but it doesn't trigger because aarch64 is missing.
    
    Fix this by adding istarget "aarch64*-*-linux*".
    
    Tested on aarch64-linux.
