    ld: fix -std=gnu23 compatibility wrt _Bool
    
    GCC trunk now defaults to -std=gnu23. We return false in a few places
    which can't work when true/false are a proper type (_Bool). Return NULL
    where appropriate instead of false. All callers handle this appropriately.
    
    ChangeLog:
            PR ld/32372
    
            * pdb.c (add_stream): Return NULL.
