    PR29676: Wildcard expansion fix for labels
    
    PR29676, introduced an bug where function symbols from the symbol
    table were expanded in the function component resulting in wildcards
    not being expanded in labels. This fix, removes the issue by restricting
    the symbol table query to probes which don't need further debuginfo to
    expand.
