    gensupport: drop suppport for define_cond_exec from compact syntac
    
    define_cond_exec does not support the special @@ syntax
    and so can't support {@.  As such just remove support
    for it.
    
    gcc/ChangeLog:
    
            PR bootstrap/110324
            * gensupport.cc (convert_syntax): Explicitly check for RTX code.
