Hmm, and we're running the test-case because aarch64 is not skipped in
skip_gdbserver_tests:
...
    # 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
    }
...
