    Allow gdb version 10 in pretty printer tests.
    
    With gdb 10, the pretty printer tests are UNSUPPORTED::
    The gdb version string (gdb -v) is incorrectly formatted.
    
    This is observable in:
    nptl/test-cond-printers, nptl/test-condattr-printers,
    nptl/test-mutex-printers, nptl/test-mutexattr-printers,
    nptl/test-rwlock-printers, nptl/test-rwlockattr-printers
    
    After updating the regexp and building with debug-info,
    all those tests are passing.
